The Xamarin Profiler product

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.

This release is now available in the Xamarin updater channels and as part of the May 10th – version 15.2 update for Visual Studio 2017.

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

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.

We are releasing the second Beta preview of our next major release, called 15.2. This release includes our next preview of Visual Studio for Mac.

Using the latest Visual Studio for Mac Preview 10 with this release is encouraged, but you can also continue to use Xamarin Studio if you prefer (though new previews of XS are not included in this release). If you are updating from Visual Studio for Mac Preview 5 or earlier, you’ll need to check for updates once to install the new Preview and then once more to get the new Xamarin Platform components. It should be noted that since VS for Mac is still in preview, it is not yet a fully supported product.

These latest Beta versions are now also available in Visual Studio 2017 Preview as part of the May 3 update (26430.01 – Preview).  The Xamarin.VisualStudio extension 4.5.0.439 in this Visual Studio 2017 Preview is one small edit behind the version in VS 2015.

As this is a Beta/Preview build, there are some known issues and the possibility of new issues being found during testing. Of course, additional bug reports are still welcome for these preview versions. If you see any suspicious behavior that you wish to report, please file a quick bug.

Work is underway to resolve those issues, but in the mean time, if you use Xamarin.iOS in Visual Studio 2017, be sure to hold off for now on trying the preview versions on the Mac. (Otherwise you will run into some incompatibility errors such as “The root assembly … conflicts with another assembly”.)

Beta 2 – March 27th 2017

Stable – This Release!

Beta Release: 15.1 Beta Preview 2

We are releasing the final Beta preview of our next major release, called 15.1. This release uses a new naming convention “15.1” that more closely resembles the sub-version numbering of Visual Studio 2017. “15.1” in this new scheme matches up with what Xamarin would have called “Cycle 10” under the old scheme.

This release is now available in the Xamarin updater channels and as part of the March 27 update for Visual Studio Preview. Note that the Xamarin version number in Visual Studio 2015 is slightly ahead of the version number in Visual Studio Preview in order to provide early availability of a few additional fixes. Xamarin coordination with the upstream schedule has been evolving across the VS 2017 releases, and plans are underway to synchronize more tightly as soon as possible. Watch for additional news on that topic as the 15.1 release moves into the Stable channel in the upcoming weeks.

Among other changes, these versions include a new experimental Concurrent Garbage Collector option for both Xamarin.Android and Xamarin.iOS.

As this is a Beta build, there are some known issues and the possibility of new issues being found during testing. Of course, additional bug reports are still welcome for these preview versions. If you see any suspicious behavior that you wish to report, please file a quick bug.
