Stable Release: 15.2.2 Servicing Release

We are releasing a service release for our current major release called 15.2, into the Beta and Stable channels.

This service release is not yet available in Visual Studio 2017. The Xamarin changes have been integrated into the upstream Visual Studio 2017 packaging process, but the service release for the full Visual Studio 2017 is still being finalized, unrelated to the Xamarin changes in particular. The Xamarin packages for Mac and Visual Studio 2015 are being published today to provide the earliest availability of the fixes for those environments.

If you notice an error in this blog post or have trouble downloading one of the installer packages, please let us know in the corresponding forum thread.


Updating from Xamarin Studio to Visual Studio for Mac

Visual Studio for Mac is now generally available as announced at the Microsoft Build conference. It is the recommended environment for Xamarin developers on Mac moving forward. To get started with Visual Studio on Mac, download and run the Visual Studio for Mac installer. It will install Visual Studio for Mac as a new app alongside Xamarin Studio.

Stable Release: 15.2 Hotfix Xamarin Android (Mac Only)

We are releasing a new stable build of Xamarin.Android to address a critical performance degradation users have experienced in the 15.2 release. This release is aimed at providing the earliest possible access to the candidate fix for the following issue for users on Mac:

56240 – [Xamarin.Android] Performance degradation in apps that use System.Linq.Expressions. Xamarin.Forms projects that use RelativeLayout are one common scenario that hits this problem.

We are working on a fix for Windows users, and hope to release that very soon.

Stable Release: 15.2

We are releasing the Stable build of our next major release, called 15.2 to the Alpha, Beta, and Stable channels.

Updating from Xamarin Studio to Visual Studio for Mac

As announced at the Microsoft Build conference, Visual Studio for Mac is now generally available. It is the recommended environment for Xamarin developers on Mac moving forward. Visual Studio for Mac has all the features of Xamarin Studio, adds cloud and web development, and contains improvements for cross-platform mobile development.

To get started with Visual Studio on Mac, download and run the Visual Studio for Mac installer. It will leave Xamarin Studio unchanged, update the other Xamarin packages to the current versions, and install the Visual Studio for Mac app. Xamarin Studio can continue to be used alongside Visual Studio for Mac if desired, but please note that debugging symbols in this 15.2 release are not backwards compatible with Xamarin Studio 6.3, so you will need to use Visual Studio for Mac to hit breakpoints and break where expected on unhandled exceptions.


Known Issues

There are some known issues and the possibility of new issues being found. Additional bug reports are still welcome for this stable version. If you see any suspicious behavior that you wish to report, please file a quick bug.

Please check out the product release notes to see all the fixes and known issues for this release.

Update for May 17: See also the list of commonly reported issues from the Xamarin 15.2 release being tracked by the Xamarin team.

  • [Android SDK Manager]55943 – “The “Aapt” task failed unexpectedly”, “Error creating start-server process”, or other errors after updating Android tools via Xamarin’s Android SDK Manager due to incorrect file permissions that cause “Native error= Access denied” for various executables.
    • Manual workaround: Add the executable flag to the “ApplicationName” indicated in the log file that is missing the executable flag, for example by using chmod in a Terminal.app command prompt.
  • [Android SDK Manager] 55720 – On uninstalling Latest build of SDK Tools, All SDK tools are uninstalled.
    • A candidate fix will be included in an upcoming preview of Visual Studio for Mac.

Technical Bulletin: Xcode 8.3 Support for VS 2017

Update: Visual Studio 2017 (26228.12) from March 31 includes Xamarin Xcode 8.3 support

Be sure to update to Visual Studio 2017 15.0.26228.12 or higher via the Tools > Extensions and Updates menu to get Xcode 8.3 compatibility for the Xamarin extensions.


Old alternate manual update steps (from March 28)

With the release of Visual Studio 2017 and the new Visual Studio Installer, there were some changes to how the Xamarin extensions for Visual Studio get installed and updated. In VS 2017, Xamarin updates will now generally be published as an integrated part of the Visual Studio Product Updates in the Extensions and Updates menu. However, the Visual Studio Product Update from earlier today (26228.10) does not yet include Xamarin’s Xcode 8.3 support. Xcode 8.3 support will instead be included in a Visual Studio Product Update for the final versions of Xamarin 15.1, which are coming soon.

In the interim, we are providing downloadable versions of the Xamarin.VisualStudio and Xamarin.iOS extensions for VS 2017 that support Xcode 8.3.  In order to use these versions, please download them from the respective links below, and follow these instructions:

  1. If by chance either file downloads with a “.zip” extension in your browser, rename it back to “.vsix” (for example after enabling the  View > File name extensions checkbox in Windows Explorer).
  2. Shut down all instances of VS 2017 currently running.  We suggest you also close any instances of VS 2015 or 2013 as well.
  3. Double click the Xamarin.VisualStudio VSIX file.
  4. A pop up window with a number of checkbox options will appear. Select only the Visual Studio 2017 checkboxes. Be sure to un-check any checkboxes present for Visual Studio 2015 and lower. Then click the install button.
  5. Once installation of the Xamarin.VS VSIX file has fully completed, repeat steps 2 & 3 for the Xamarin.Apple.Sdk VSIX file.
  6. Once installation of both Xamarin.VS and Xamarin.iOS are complete, restart VS 2017, and confirm the new Xamarin and Xamarin.iOS extensions are installed by checking the versions listed in Help > About Microsoft Visual Studio.

If you see a behavior that looks suspicious in these versions, and if it isn’t clear whether one of the known issues in the release notes matches the problem, please file a quick bug report to let the team know.

If you notice an error in this blog post or have trouble downloading one of the installer packages, please let us know in the corresponding forum thread.

Uninstalling this Update from Visual Studio 2017

In the event that these versions need to be uninstalled, the Visual Studio Installer can be used to accomplish this. Read the uninstalling Xamarin guide for more information.

Note that uninstalling these manually installed VSIX files through this process will fully remove the Xamarin.VisualStudio extension from VS 2017. You will need to re-install the Xamarin component through the Visual Studio Installer to restore the previous Xamarin 4.3.0.784 version in VS 2017.

Stable Release: Cycle 9 SR0 with Xcode 8.3 Support

We are releasing an update to our current stable builds of Xamarin Studio, Xamarin for Visual Studio, and Xamarin.iOS. These new builds offer Xcode 8.3 support, for the Xamarin.iOS SDK and the Xamarin iOS Designer. In addition, we have addressed an intermittent NullReferenceException crash that could occur when canceling NSUrlSessionHandler HttpClient.SendAsync() requests via CancellationTokenSource.Cancel() in iOS projects (53794).

For Visual Studio 2017 users, be sure to update to Visual Studio 2017 15.0.26228.12 or higher to get the new versions of the Xamarin extensions.

If you see a behavior that looks suspicious in these versions, and if it isn’t clear whether one of the known issues in the release notes matches the problem, please file a quick bug report to let the team know.

If you notice an error in this blog post or have trouble downloading one of the installer packages, please let us know in the corresponding forum thread.
