New in Xamarin Studio 6.1.2.44-0 (Nov 14, 2016)

New in Xamarin Studio 6.1.1.15-0 (Sep 27, 2016)

New in Xamarin Studio 6.1.0.5441-0 (Sep 16, 2016)

NUGET:
Can now install a specific NuGet package version from the Add Packages dialog by selecting the version from a Version combo box.
Project's can now use a project.json file instead of a packages.config file. The project.json file is a new package file format introduced with NuGet 3 which supports transitive restore. More detailed information on project.json can be found in the NuGet documentation. The project.json file needs to be added manually and the project closed and re-opened before the project.json file is used in Xamarin Studio.
The version of NuGet supported is now displayed in the About dialog when the Show Details button is selected.
When adding a new NuGet package source a browse button has added to the Add Package Source dialog which can be used select a folder so a local package source can be created without having to type in the folder name.
Add Package Source dialog has been changed to make it more obvious that either a URL or a folder can be used as a package source. The URL label has been change to Location and the placeholder text now specifies that a URL or a folder can be used.
A NuGet package can now be removed when it not restored and is unavailable from all package sources. When the NuGet package removal fails a dialog will be displayed allowing the NuGet package to be removed by force. If the option to remove the NuGet package is then selected Xamarin Studio will then remove the package from the packages.config file, remove any references and imports for the NuGet package from the project file.
Custom package sources are now only read from the global NuGet config file under ~/.config/NuGet/NuGet.Config. Per-solution NuGet.Config files located in individual solution directories are no longer read. This matches the behavior of the NuGet package manager in Visual Studio.
Added support for NuGet 3:
NuGet 3's package source is now supported - https://api.nuget.org/v3/index.json.
NuGet packages that only support NuGet 3 or above can now be installed.
C# REFACTORINGS:
Refactorings and code diagnostic fixes are no longer shown inside the context menu, instead the ‘Quick Fix’ command is shown. All fixes and diagnostics are shown when that command is selected.
Refactoring previews are shown inside the Quick Fix command list when a code action is selected.
There is a new menu inside the project Menu called ‘Analyze’ this allows to run the analyzers on the whole solution or individual project. Analyzers results are shown in the error list.
When adding NuGet packages that contain analyzers (like Async Method Analyzer) the analyzers are shown inside the project tree under References/Analyzers and are being run as part of the background code analysis.
F# SUPPORT:
Code completion and syntax highlighting fixes.
All operations that require parsing the project file are now much faster.
F# interactive improvements:
Code completion
Parameter hints
Text zooming
Load / save as fsx script
ANDROID DESIGNER:
Because of an Android upstream issue, support for rendering API 24 is not available in this release
Custom controls support:
The Android designer now supports loading both Java-based and .NET based custom controls referenced in layout files.
Custom controls can be edited like any other control in the property panel, including custom properties defined in a resource entry of the same name. You can also drag and drop them directly from the toolbox where two new categories, Custom Controls and Support Libraries, have been added for convenience.
Android Designer:
Android designer rendering a layout containing several support libraries components (AppBarLayout, Toolbar, RecyclerView, CoordinatorLayout, ...) and custom widgets implementation.
New toolbox icons:
The toolbox has been visually refreshed with new icons that fully support Xamarin Studio new dark/light themes.
Others:
Performance optimizations around loading time and property panel interactions.
RecyclerView now supports the 'listitem' design property (of type layout) to allow mocked data display.
Support DrawerLayout design attribute 'openLayout' to allow visualization of a drawer content.
IOS:
Xamarin Studio now includes all new iOS 10 extensions templates covering new framworks such as CallKit, Messages, ReplayKit, SiriKit and UserNotifications. A new asset type has been added for iMessage apps: the stickers icon set letting you add iMessage app icons. In addition to that we've added support for tvOS extensions which also have some dedicated templates, including one to modify Top Shelf images at runtime.
IOS DESIGNER:
We've been hard at work improving performance, reliability and accuracy. We have full support for Xcode 7.3 and iOS 9.3 with hundreds of changes to improve design time experience, especially for widgets like UIStackView.
The highlights for this release are:
The attributed string editor has been reworked to improve many aspects of it’s behaviour, including a beatiful new color picker.
The ‘Shows Toolbar’ property should be respected for every type of View Controller now
Fixed several rendering glitches in WatchOS storyboards.
Significantly improved the performance of code generation using Roslyn.
Many changes to improve responsivity when interacting with the property panel.
Resizes handles should now show up in the right places when in Xib mode.
The designer respects the RegisterAttribute.SkipRegistration property when loading custom controls.
Added missing support for the primaryActionTriggered event in tvOS storyboards.
Malformed/corrupt images should never crash the designer now.
Added missing support for the TargetAction for various Gesture Recognizers.
Views that are marked as Hidden are no longer hidden on the design surface, they are faded out instead. This makes it significantly easier to work with views which are not visible by default.
Full support for all tvOS simulated metrics.
Fixed a layout issue when adding a TitleView to a UINavigationItem.
XAMARIN FORMS PREVIEWER:
We're proud to annouce a sneak peek of the new Xamarin Forms Previewer. This renders xaml as you type so you can see exactly how it will look on iOS or Android. It has support for loading and executing custom renderers, so your platform specific UI modifications will show up in the previewer.
You can access the previewer by opening a xaml file and then clicking on the Preview button in the top right. You will need to install the latest Xamarin.Forms nuget for the Previewer to function.
RUN CONFIGURATIONS:
Most project types currently have options you can set to customize how you want to run an application. For example, in a console project you can specify command line arguments or environment variables.
In this release we are introducing the concept of Run Configurations. A run configuration is basically a set of execution options with a name, and you can define several configurations in a project for different purposes.
Run configurations are defined at project level. You can choose to share configurations with other developers (in which case the configurations will be stored in the .csproj file) or to keep them for yourself (in which case they will be stored in a .user file). Projects will always have a default run configuration, but you can add as many as you want.
Some run configurations are automatically generated. For example, iOS projects with support for Background Fetch will offer a run configuration for starting the project in Background Fetch mode. Projects which contain unit tests will have a configuration for running the tests.
To make it easier to select which run configuration you want to use to execute a project, we have added a new selector to the toolbar, next to the build configuration selector.
Android Run Configurations:
Run Configurations for Android projects allow you to specify which activity, service or broadcast receiver to launch when running or debugging the project. You can pass intent extra data and set intent flags to be able to test your components under different launch conditions.
Activities other than the MainLauncher will need to have Exported=true added to the Activity attribute for debugging on a physical device, or have Intent filters defined.
VERSION CONTROL:
Performance improvements to status queries.
Performance improvements to the tag dialog.
Submodules now show the short SHA in the solution pad.
COMBINED DEVICE LOG:
The separate Device Logs for iOS devices and for Android devices have been combined into a single device log. This now gives the ability filter iOS logs in the same way that Android logs could be filtered.
Both iOS and Android devices show in the list of devices. Events can be filtered by severity (Error, Warning, Info) or by ‘Tag’. It is possible to drop Markers in the log to help navigate back to a particular moment.
USABILITY IMPROVEMENTS TO THE MENU BAR DESIGN:
We’ve taken a look at most menus in the menubar and redesigned them to adhere to OS X’s human interface guidelines. Features are now grouped together where it makes sense, have more descriptive names, and are made more discoverable.
SYSTEM FONT:
On Mac we now use the system font for user interface elements, allowing us to use San Francisco font on El Capitan.
LOCALIZATIONS:
Thanks to the localization team at Microsoft we now have 13 fully localized translations for Xamarin Studio.
The supported languages are: * Chinese Simplified * Chinese Traditional * Czech * French * German * Italian * Japanese * Korean * Polish * Portugese (Brazil) * Spanish * Russian * Turkish
KEYBOARD BINDINGS:
Added multiple binding support
New binding conflict detection
Updated Visual Studio binding scheme
Added new binding schemes on Mac:
ReSharper / Rider
Visual Studio
Visual Studio Code
Xcode
MSBUILD SUPPORT:
Thanks to the open sourcing of Microsoft MSBuild last year, the msbuild command has been fixed to run on Mono and it is now available on Mac. This release includes experimental support for building projects using MSBuild on Mac, instead of using Mono's xbuild. We plan to make this change permanent in future releases. This option can be enabled in the global preferences, in the Projects / Build section.
NEW "EXCEPTION CAUGHT" DIALOG:
User experience is greatly improved when exception is caught and dialog "Exception caught" is shown. List of changes:
Navigating to inner exceptions is much easier via navigation tree on right side of dialog
Properties of exception object are all flattened, so no need to navigate to base class to see all properties
Stacktrace is more compact which allows displaying more stack frames
Stacktrace hides external code frames, making stacktrace more readable

NEW PROJECT DIALOG:
The window for creating new projects has been redesigned in this release. The new window has been designed as a wizard that allows creating a project in several steps: template selection, platform-specific options and generic project settings.
Template Selection:
The new window presents a new category hierarchy that makes it easier to find specific templates. Template categories are organized in two columns. The first column allows selecting the platform (iOS, Android, Mac or cross-platform) and also the kind of project (app, library or test). The second column shows the list of templates.
When a template is selected, a badge with the language name is shown in the template row. If the template supports more than one language, the badge allows selecting the language to be used for the new project:
The right side of the window shows an image and a description of the template.
iOS Project Options:
Instead of having different sets of project templates for iPhone, iPad and Universal, the new window presents a single set of templates which can be used for creating projects for any device. The target device (or devices) can be selected in a configuration page of the project creation wizard:
The wizard also allows selecting the target iOS version. Notice that the target version may also have an effect on the new project. For example if iOS 8 is selected as the minimum target, the code generated for the new project will use the new iOS 8 template using size classes. This allows to have only one storyboard instead of our previous two storyboard (iPhone/iPad).
WatchKit Project Options:
The new WatchKit wizard allows you to select the parent iOS project that will reference the two WatchKit templates created for you. Everything is now done automatically, from the references between the projects to the bundle identifiers fixed for you.
You can also choose if you want to support Glance or Notification from the wizard. That will generate the storyboard views as well as the controller files for the selected scenes.
Android Project Options:
The Android wizard offers several configuration options, such as the target version and the theme, and it also allows adding a predefined set of commonly used components.
Xamarin.Forms Project Options:
The Forms (or Cross-platform) wizard allows selecting the platforms we want to support, as well as the kind of library to be used for sharing code.
Project Creation:
The final page of the wizard allows entering the name of the project and the solution, and its location on the hard disk. There are also options for initializing a local git repository for the project. The Preview pane at the right shows how files will be organized on disk after creating the project.
PUBLISHING WORKFLOW:
This Xamarin Studio Release includes a new integrated workflow for publishing iOS, Android and Mac apps.
The main goal of this new workflow is to provide a simple, straightforward, and consistent way to organize and publish app releases to the different app stores, with support for ad-hoc and enterprise packages.
Another goal is to reduce the number of build configurations that users have to manage by re-signing binaries instead of having to use a build configuration with different signing options. This means that the AdHoc and AppStore iOS configurations are not required anymore.
This new feature replaces the old iOS specific Archives view and the Publish to TestFlight command.
Creating an Archive:
The process of publishing an app starts by running the "Archive for Publishing” command on a project:
This command is now available for iOS, Android and Mac projects. There is also an "Archive All” command in the context menu of the solution, which can be used to create archives for all projects of the solution. For this command to work, you must select a Release configuration.
The command will build the project and will create an archive, which will be shown in the new Archives View.
Archives View:
The Archives view shows all archives that have been created, grouped by solution. By default this view only shows the currently open solution. If you want to see all solutions that have archives, click on the "Show all archives” option.
The view can be opened by right-clicking on a project or solution and selecting the "View Archives” option, or using the same command from the Build menu in the main menu bar.
When a solution is selected, the view shows a list of all archives created for the solution, with information about the target platform, version, creation date. There is also an editable comment column.
When an archive is selected, the bottom section of the view shows information about the archive, and then the "Sign and Distribute” button can be used to publish the package.
The context menu of the archives list can also be used to distribute an archive, or to delete it.
Publishing an Archive:
An archive can be published by selecting it in the archives list and clicking on the "Sign and Distribute” command. You can also double-click on the archive.
The steps and information required for publishing a package depends on the target platform and channel, but in general in process involves the steps described in the next sections.
Channel Selection:
The following distribution channels are supported for iOS:
AppStore: generates a package.
AdHoc: generates an IPA.
Enterprise: generates an IPA.
Android distribution channels:
Google Play: generates a package and uploads it to a Google Play account.
AdHoc: generates an APK.
Mac distribution channels:
AppStore: generates an AppStore package.
Mac app bundle: generates a .app bundle.
Mac installer package: generates a .pkg installer.
Package Signing:
The wizard will show a list of signatures or profiles that can be used to sign the package for the selected distribution channel (notice that not all signatures are valid for all channels).
If the package is already signed, there will be an option for keeping the current signature.
For Android packages there is an option to create a new key, or add an existing key to the Xamarin Studio key storage. Keys can also be managed in the Android Signing Keys options panel in the Xamarin Studio preferences.
Channel parameters:
Some distribution channels will require additional information.
Google Play distribution requires a Google Play account. If a Google account has not yet been registered, the wizard will ask for the account Id and secret, and this information will be stored so that it can be reused when distributing other apps. Accounts can be managed at any time in the Google Play Accounts options panel, in the Xamarin Studio Preferences.
It is also possible to select the track where to upload the package (Alpha, Beta, Rollout or Production).
Package publication:
Some channels (such as Google Play) have support for package uploading to registered accounts, so in this step the package will be generated and uploaded.
For channels that don’t have this possibility, the package will be generated and then saved to disk. The user can then manually upload the package.
TEST CLOUD:
Standalone UITest project templates provided for Android, iOS and Cross-Platform.
Android, iOS, Xamarin.Forms and Cross-Platform project templates now include a UITest project with a UITest that tests the main application.
UITest projects can be run locally with the iOS and Android device or simulator with the test results shows in the Unit Tests window.
UITests will run with the device or simulator (Android or iOS) selected in Xamarin Studio.
Run in Test Cloud menu added to the Unit Tests window to allow UITests to be uploaded to Test Cloud.
IMPROVED DEBUGGER EXPERIENCE:
New Debugger Visualizers:
This release includes a new UI for quickly visualizing the value of a variable, field or property while debugging. The new Preview popup is supported for some specific data structures: strings, points, sizes, rectangles, colors, map locations, images, bézier curves, among others.
IEnumerable Expansion:
It is now possible to see the values returned by objects that implement IEnumerable. A new IEnumerator node is shown for those objects.
When this node is expanded, the enumerator is evaluated and the returned values are shown in the tree.
XAMARIN.ANDROID:
This release includes new build options for Xamarin.Android 5.1 features:
AOT Support (Ahead Of Time compilation) to reduce JIT startup overheads.
Multi-Dex Support: Multi-Dex support enables use of new Android SDK tools ("jack” and "jill’) to bypass the historical 64k method limit present within the .dex file format.
Arm64 Support: Xamarin.Android 5.1 adds support for targeting 64-bit Android platforms such as the Nexus 9.
ProGuard Support: ProGuard is an Android SDK tool which can be used to link and obfuscate Java code. The primary reason to provide ProGuard support is to permit smaller applications, so that gigantic libraries such as Google Play Services can be reduced in size.
TEXT EDITOR:
Partial C# 6 Support:
Mono 4.0 includes support for C# 6, and although Xamarin Studio doesn't yet fully support code completion and refactoring operations for all C# 6 constructs, it will now work for some of them.
Preview of editor settings changes:
When changing the configuration of the text editor in global preferences (such as the font, color, visible markers, etc), the changes will be immediately visible. This makes it easier to see what's the effect of some settings in the look of the editor.
NATIVE MAC TOOLBAR:
Xamarin Studio on Mac now has a toolbar with a native look and behavior. On Yosemite, the new toolbar blends with the title bar, thus providing more vertical space in the work area.
NUGET SUPPORT:
The Packages folder is now always visible in Solution pad.
Target Framework changes are now detected on project reload. The iOS Classic to iOS Unified migration tool changes the project’s target framework in the project file. Xamarin Studio will now detect this has been changed and the NuGet packages will be checked for compatibility with the new target framework.
Updated to NuGet 2.8.3: it allows NuGet packages that explicitly target NuGet 2.8.3 or use the new ASP.NET Core target frameworks to be installed into a project, such as xunit.
CONFIGURABLE COMPONENTS DIRECTORY:
A project can now specify a directory where Xamarin Components will be extracted to before being referenced by a project. This allows multiple solutions to use the same directory and prevents the assembly references from being modified when a project is opened within the context different solutions.
SKETCHES:
New View Options:
There is a new "Sketch" layout available in the View menu, which includes the new Sketch Properties pad. The pad can also be toggled from View → Pads → Sketch Properties.
You can toggle the display of the Console Output in the sketch timeline with View → Sketches → Console Output.
You can restore all CaptureValue visualizers for a sketch with View → Sketches → Restore CaptureValue Visualizers.
Resource Management UI:
In Xamarin Studio 5.7, we introduced the ability to add resources to your sketch files by creating a folder called "{yoursketch}.sketchcs.Resources". Now, this can all be managed from within Xamarin Studio.
The Sketch Properties pad shows the contents of your sketch's resources folder. You can add and remove resources right from the pad by right-clicking the Resources folder, or by dragging and dropping files into the folder.
If your sketch is in a project, you can also manage your resources in the solution explorer, by expanding the sketch file node to reveal the resources folder node within it. Be aware that if you delete a sketch in Xamarin Studio, the resources folder will also be deleted.
On iOS and Mac, resources are exposed via NSBundle.MainBundle. However, keep in mind that some Apple APIs cache resources. So, if you access an image using NSImage.ImageNamed(resourceName), and then modify the image, you won't see the changes in the sketch, because NSImage caches by name. To work around this, use NSBundle.MainBundle.ImageForResource(resourceName), or new NSImage(GetResourcePath(resourceName)).
Improved Security:
If you downloaded a sketch from the internet, we will not execute it until you approve it.
Xamarin.Forms Sketches Upgraded:
Xamarin.Forms 1.3.2 contains many bugfixes. Your Android and iOS Xamarin.Forms sketches can now use new features like element styles.
Other changes:
When a Mac sketch file is open, a dock icon now appears from the agent app (the process that actually evaluates sketch code). This makes it easy to bring the RootWindow back to the foreground, or quit the process if it's causing problems.
IOS DESIGNER:
Fixed a crash caused by clicking on the 'Events' tab of a custom control when the corresponding source code for that class is missing
The labels have been restored to all the properties which were missing them
Improved support for unwind segues in the property panel
Improved the initial loading performance of large storyboards
Fixed more cases where incorrect resize handles were showing
Improved rendering accuracy when using NavigationBar or TabBar simulated metrics
WKInterfaceSwitch and WKInterfaceSlider will now have default 'click' actions in the Events panel
Improved property panel support for the 'Storyboard ID', 'Restoration ID' and 'Use storybosard id as restoration id' properties
The 'Identity' panel shows up for Custom NSObjects again
Many minor performance improvements for common situations like opening a storyboard, syncing the generated code and re-rendering after changing a property.
Improved rendering accuracy for NSNotificationCategory
It is now possible to use drag and drop on the design surface to re-order UITableViewCells
OTHER FIXES AND IMPROVEMENTS:
The Welcome Page now shows a Start Trial button when a trial is available.
The Help menu now has links to the release notes of every installed Xamarin product.
Updated Japanese translation.

New in Xamarin Studio 5.7.1.14-0 (Jan 26, 2015)

New in Xamarin Studio 5.7.0.660-0 (Jan 21, 2015)

GENERAL:
Xamarin Studio on Windows now uses the Taskbar icon to display global task progress.
Improved organization of global preferences. The C# options for source analysis have been moved from the Soruce Code section to a node below Text Editor / Source Analysis.
Improved the edit reference dialog. The tab for selecting an assembly now shows a list of recently selected assemblies instead of the file selector. There is now a Browse button which can be used to select new assemblies.
The startup project name is now stored in the user solution settings file instead of the .sln file.
Find in Files command is now much faster and uses less memory when there are many hits.
Application output (and other output pads) now have a Search command.
ANDROID:
Android Package Signing - Property Page:
Package signing properties for an Android application project can now be set without having to manually edit the .csproj. This is only for Release configurations, as the "Create Android Package” and "Publish Android Application” commands are only available for Release configs.
Android Designer Improvements:
Auto-completion support for layout XML files.
Preview support for some XML layout attributes.
Rendering support Wear round.
Fixed crash when opening a lot of layout files.
Fix "jumping” visual glitches when selecting items.
Aapt errors are now correctly handled and double-clicking them will bring you to the right file/line combination
Version chooser will now show values between manifest's minimum API level and target API level
Other Android fixes and improvements:
Android Apps fail to launch on Lollipop devices when in Release mode with Shared Runtime/FastDevelopment on.
CLASSIC TO UNIFIED API CODE MIGRATION TOOL:
The Project / Migrate to Xamarin.iOS and Xamarin.Mac Unified API menu item now also (partially) migrates project source code to the new API. The following types of changes will be made to the project source code:
Statements such as ‘using MonoTouch.Foundation;’ will be modified to ‘using Foundation;’.
Usage of System.Drawing types (RectangleF, PointF, and SizeF) will be migrated to their respective CoreGraphics equivalents (CGRect, CGPoint, and CGSize).
Method overrides on subclasses of MonoTouch classes will be migrated to match their new prototypes.
CFRunLoop constants will be migrated to their new names.
Calls to DismissModalViewControllerAnimated() will be updated to call DismissModalViewController().
Calls to PopViewControllerAnimated() will be updated to call PopViewController().
Calls to CGContext.SetShadowWithColor() will be updated to call CGContext.SetShadow().
Calls to CGContext.SetRGBFillColor() will be updated to call CGContext.SetFillColor().
IOS:
Fixed archiving of iOS apps with App Extensions (dSYMs and the archived-expanded-entitlements.xcent files are both archived now).
iOS Simulator configurations now default to i386-only for Unified API projects rather than i386+x86_64 to improve build times.
Added support for choosing vector images (.pdf’s) for Image Assets.
The Info.plist LaunchImage editor now defaults to requesting full-screen images for iOS >= 7.0 instead of the image sizes with room for the status bar.
When syncing back from Xcode, *.build directories are now ignored.
Fixed Asset Catalog compilation for iOS Library Projects w/o an Info.plist
Fixed archiving to pick the correct icon to use in the Archive Organizer window.
Fixed the Asset Catalog editor to properly serialize the json for image sizes. (bug #24164)
Fixed the Info.plist scheme for NSExtension (for use with the Source tab of the Info.plist editor).
Launch file dropdown in project properties is now alphabetically sorted.
Application bundle names and the native executable names now use the AssemblyName value (from the .csproj file) as opposed to a sanitized version of the MSBuildProjectName value. This means that if the AssemblyName has periods, then so will the application bundle directory name and the native executable name within the app bundle. (bug #1532)
IOS DESIGNER IMPROVEMENTS:
Full support for Xamarin.iOS Unified projects.
SCNView, UIScreenEdgePanGestureRecognizer, UIVisualEffectView, UISplitViewController are all fully supported now.
Significantly improved support for UICollectionView and UICollectionViewLayout.
Added support for aspect ratio based constraints.
UITabBarController will no longer randomly disappear when creating new Tab segues.
Removed the ability to delete the NavigationBar from a UINavigationController. iOS will crash at runtime if you try this.
Constraints can now be exposed as an Outlet or custom class.
Fixed an issue changing the style of a UITableViewCell when constraints are disabled.
Fixed several issues where the property panel would write incorrect Xml to the storyboard.
Custom fonts are fully supported by the design surface and font picker.
Fixed a case where old assemblies were sometimes used to render custom controls.
Embed segues can now be created from Container Views.
Fixed an rare issue where views with zero width or zero height could break the designer.
Fixed a crash when deleting the segments inside a Segmented Control.
Custom properties of type 'float' and 'double' should work now.
Elements inside a UIScrollView will no longer change their position every time we render the storyboard.
Added support for UITextAlignment.Justified and UITextAlignment.Natural
Fixed an exception when right clicking on a Size constraint
The localization ID for UIView/UIViewController is displayed in the property panel now.
Improved support for UIViewController.PreferredStatusBarStyle.
MAC:
Full framework support for Xamarin.Mac:
Unified API applications now support building against full desktop .NET frameworks in addition to the default Xamarin.Mac mobile framework. Full frameworks/profiles are completely unsupported by Xamarin, but this option now exists to help legacy applications port to the mobile framework while still taking advantage of all the new features in Unified API.
The target framework can be changed from Xamarin.Mac mobile to full desktop .NET under the regular Project Options → Build → General → Target Framework UI.
Other Mac fixes and improvements:
Fixed Info.plist editor to allow setting storyboard files as the Main Interface (bug #23997)
Added UI for using the new ref-counting mechanism in the Mac Build Settings.
SKETCHES:
New visualizations:
Mac/iOS: CGPoint, CGRect, CGSize, CGPath, NSBezierPath, NSFont, CGFont, NSColor, CGColor, NSUrl, NSAttributedString, NSGradient, CGGradient, CGLineCap, CGLineJoin, CGImage, NSImage, NSView, NSButtonType, CIColor, CIImage, CICrop, UIImage, UIView
System.Drawing: Point, PointF, Size, SizeF, Rectangle, RectangleF, Color, Image, Brush, Font, Pen
Android: Point, PointF, Rect, RectF
BCL: Uri, enums
Resource bundling:
Resource bundling is now supported. Resources can be accessed in iOS and Mac directly from the main NSBundle (e.g. direct use of say NSImage.ImageNamed is now supported).
There is not yet a UI available for embedding resources, however if a Sketch has the name MySketch.sketchcs, then you can create a directory next to the file called MySketch.sketchcs.Resources, and any files in that directory will be available within the sketch. A general purpose API for all platforms is GetResourcePath(string resourceName). This will return a full path to a resource, and is the only way to access a named resource on Android currently. NSBundle.MainBundle can be used as expected on Mac and iOS.
File format changed to Markdown:
The file format for a Sketch is now Markdown. While there is no immediate benefit to this, we will be taking advantage of Markdown features in the future and wanted to stabilize sooner than later on the basic file format.
Metadata (e.g. resource information) is stored within an XML code fence, followed by C# or F# in respective code fences. While arbitrary Markdown content outside of fences should be preserved, it will not be displayed inside Xamarin Studio. We still recommend only editing Sketch files in Xamarin Studio.
Classic iOS API not supported:
The Classic iOS API is no longer supported. Sketches will focus only on the Xamarin iOS and Mac Unified API going forward as Apple will be phasing out 32-bit iOS applications completely soon. Xamarin.Forms sketches are now available under the Unified iOS API.
OTHER FIXES AND IMPROVEMENTS:
Android support is much more stable: we fixed a networking issue that was very apparent under Android while much less so under Mac and iOS.
Mac support now has a RootWindow property defined for exploring live Cocoa UI.
Multiple Sketches with the same platform target (e.g. iOS) may now be opened at the same time within Xamarin Studio
.sketchcs and .sketchfs files are now registered to open with Xamarin Studio
Many other bug fixes and stability improvements have been introduced since the Xamarin Studio 5.6 Evolve preview.
VERSION CONTROL:
Fixed crash when opening a project that uses an incompatible Subversion Working Copy format.
Several optimization and fixes in the Version Control status view.
Version Control Log view now displays a default icon for emails which aren’t linked on Gravatar.
Fixed: Xamarin Studio crashes when viewing SVN log on Mac OS.X 10.10.
NUGET:
Menu options for add-in NuGet packages have been renamed to make them easier to discover, so for example instead of "Add Package" we now have "Add NuGet Package".
Error and warning icons applied to packages are now more consistent with other icons in the solution pad.
Fixed: Xamarin Studio doesn't recognize that files exist after NuGet Update.
Fixed: Update all Packages in Solution not Updating Dependencies.
Fixed: Unable to add NuGet package again after removing it.
PROFILER:
Profiling works for F# apps
Integration with Xamarin Profiler has been added for iOS and Android applications. To start profiling an application, you can use either the Run menu or Right click on a project and select Start Profiling. You can also launch the profile as a standalone application from Tools -> Launch Profiler.
New options to enable developer instrumentation have been added into Android and iOS projects’ Build Options. These are not retroactive and you will be asked to enable them if the project’s build configuration doesn’t have them when profiling is requested for it.
DEBUGGER:
Hex debugger visualizer now shows a wider range of characters.
Fixed: Cannot use typeof operator with type parameters.
Fixed: New breakpoint dialog shows Unix filepath example on Windows.
Fixed: Debugger reports a 'System.NotSupportedException' exception when using Set Next Statement command.
Fixed: Variable called dynamic confuses debugger.
SOURCE CODE EDITING:
Fixed: Unable to remove custom code template.
Fixed: Semicolon is put at the end of line instead at the position of cursor.
Fixed: Sort usings yields strange result
Fixed: Navigate Forward/Backward may cause a crash when used in rapid succession.
Fixed: Editor tooltips overlay new windows.
Fixed: Completion is not working for 'is' statement.
Fixed: Rename refactoring command fails with InvalidCastException on generic class name after 'new'.
Fixed: Xamarin Studio not recognizing reflection extensions in PCL when Microsoft.Net.Http is present.
Fixed: #define code showing as comments if symbol is not declared in build options.
Fixed: Folding markers not correctly shown when the columns for #region and #endregion differ.
Fixed: C# string property in object initializer autocompletes to #if.
Fixed: Cannot open .cshtml files.
OTHER FIXES AND IMPROVEMENTS:
Fixed: After the Update was installed, Windows did a forced restart.
Fixed delay when opening the project context menu.
Fixed: Deleting a folder in the solution pad does not result in the folder being removed from the tree.
Fixed occasional crash when deleting a solution folder while the properties pad is visible.
Fixed: Copying info in the test output window results in wrong text being copied.
Fixed: Xamarin Studio throws exception on doing Export Policy to specific file.
Fixed exception while creating VBNet->NUnit Library Project.
Fixed: Cannot change font of the Test Results pad (e.g. to monospace font).
Fixed: Nunit runner has trouble when class with TestFixture is defined without a namespace.
Fixed: Time summary not correctly shown in Unit Tests pad.
Fixed T4 TextTransformation interface issue with Initialize.
Fixed: T4 ignores output directive if PreprocessTemplate() is used.
Fixed: 'Load previous solution on startup' option breaks loading projects from the command line.
Fixed: Removing reference to a shared project from project references causes UI freeze.
Fixed: Enabling MSBuild Support in a Xamarin.Forms Shared Project doesn't build.
Fixed: [Windows] Xamarin Studio Updater window displays wrong number of installing updates.
Fixed: Go to Definition opens the assembly browser, but does not show the correct type.
Fixed: File appears twice when searching.
Fixed: "Add Package Source" popup window should remain at top.

Fixed: when editing the android application settings via the property page it sets the manifest encoding to windows-1252.
If your Android project was targeting the Android L Preview, you'll need to update your Android XML manifest to change version information from L to 21. Additionally, you should retarget your project's framework to use version 5.0 or, alternatively, set it to use the latest available framework version.

New in Xamarin Studio 5.5.0.227-0 (Oct 7, 2014)

New in Xamarin Studio 5.4.0.240-0 (Oct 7, 2014)

New in Xamarin Studio 5.0.1.3 (Jul 3, 2014)

Shell:
The Xamarin Studio shell has been reviewed to make sure it looks awesome in retina displays. We have new beautiful icons and a number of other visual enhancements like the new welcome page, fine-tuned toolbar status bar, about dialog and Windows splash.
NuGet Support:
NuGet support is now included by default in Xamarin Studio, with a brand new user interface. The new Add Packages dialog allows NuGet packages to be searched for and installed into a project.
Add Packages Dialog can be opened using the Project → Add Packages menu option, or from the Solution pad by right clicking the project and selecting Add → Add Packages, or by right clicking the Packages folder and selecting Add Packages. Double clicking the Packages folder also opens the dialog.
In the top right of the dialog is the search text box. The Add Packages dialog will search for packages as you type. Alongside the normal free text search, the search text box supports searching for packages by the ‘tags’, ‘id’, ‘description’ properties if the package source supports these. For example: "id:NUnit", "tags:fsharp", "description:mono". Recently used packages are shown first in the packages list for the current Xamarin Studio session.
NuGet packages installed in a project are shown in the new Packages folder, under the project node in the Solution pad. References added by packages are shown in the new "From Packages" folder under the References folder, under the project node.
NuGet packages will be automatically restored on opening a solution. Automatic NuGet package restore can be enabled/disabled in Preferences / Packages / General. NuGet package restore can be started manually by selecting Project → Restore Packages, right clicking the solution and selecting Restore Packages, or right clicking the Packages folder and selecting Restore.
Package sources can be configured in Preferences / Packages / Sources. Double click a package source to update an existing source. To reorder the packages, drag and drop a source in the list. Package source credentials can be configured for feeds that require authorization. Invalid credentials or package source urls will be highlighted in the list of sources.

New in Xamarin Studio 4.3.1 Alpha (Jan 11, 2014)

New in Xamarin Studio 4.3.0 Alpha (Dec 18, 2013)

New in Xamarin Studio 4.2.2 (Dec 18, 2013)

New in Xamarin Studio 4.2 (Dec 18, 2013)

iOS Developer Account login required:
Starting with Xamarin Studio 4.2, you will be required to log into your Apple Developer Account in Xamarin Studio
You can access the Developer Account settings page by navigating to Xamarin Studio -> Preferences -> Developer Accounts:
Source Code Editing:
Improved support for on-the-fly formatting and indenting.
Improved source analysis (beta), with better performance, memory use and stability.
Fixed several issues when editing aspx and xml files.
Improved handling of files with mixed line endings.
Improved the look of in-line error bubbles.
Reloading a modified file from disk and restoring from Autosave are now undo-able actions.
Fixed F# syntax highlighting issues
Improved the speed and user experience of the import symbol completion
iOS:
Added right-click context menu on *.xcassets directories to add individual asset catalogs for images, app icons, and launch images.
Added an “archive” command for mdtool which does the same thing as the Build / Archive menu item in Xamarin Studio.
Updated all of the iOS project Storyboard templates to default to the new Xcode 5 format.
Added code completion support for the new Xamarin.iOS protocol support in C#. Xamarin Studio is now aware of bindings to Objective-C protocols. This means that when your class implements one of the C# interfaces that map to an Objective-C protocol, when you use the “override” keyword it will offer not only to complete the methods inherited from base classes and interfaces, but will offer also the optional methods from the Objective-C protocol. More information about the new protocol support in Xamarin.iOS is available in the Binding Objective-C Libraries document.
Android Designer:
The Android Designer is now better in handling layouts with multiple alternative versions. When opening a layout that has multiple versions, those are shown as thumbnails in a side bar. The designer now has two operation modes. In the default mode, changes done to a layout version are particular to that version and won’t have any effect on the other versions. When in multi-edit mode, several layouts can be selected for synchronized editing. Changes done in one layout will be propagated to all selected layouts. Support for change conflict resolution when in multi-edit mode has also been improved.
Other improvements include:
Several improvements in the toolbar and property grid.
The stock device list available in the toolbar now shows the devices defined in the Android SDK. Those devices can be configured in the Android Emulator manager.
Improved performance. The designer is now more responsive when working with big layouts.
Version Control:
Added commands for tagging branches, removing and push tags (Git).
Fixed incorrect repository detection issue (Git).
Fixed error when adding Web References in a Subversion repository.
Improved progress monitoring and notifying for Subversion on Windows.
Added option for disabling version control support globally.
Debugger:
Improved support for visualizing big arrays using the hex visualizer (data is now incrementally fetched)
Allow stepping into autogenerated enumerators in user assemblies
Improved stability when debugging on the Microsoft .NET CLR.
Project System:
Xamarin Studio now can properly load and interpret projects which make use of properties and environment variables in the definition of project items.
Fixed bug that caused classes from System.Core and PCL framework assemblies to not be shown in code completion
Improved PCL profile selection panel
Implicit PCL framework references are now shown in the solution pad.
Xamarin Account Management:
The license activation process has been greatly improved.
There is no need anymore to log-in using a web browser.
