Stable Release: 15.1

We are releasing the Stable build of our next major release, called 15.1 to the Alpha, Beta, and Stable channels.  The 15.1 release name follows the Microsoft VS release naming convention.

This release is now available in the Xamarin updater channels and as part of the April 5th 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.


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.

  • [Xamarin.VS]54465 – Object reference not set to an instance of an object when building Master Detail Forms Shared iOS project template.
    • The current workaround is to rebuild the solution again. Please stay tuned for resolution details.
  • [Xamarin Studio]53906 – Fastlane showing nothing from Apple subscriptions and not updating.
    • The team details dialog is empty. In certain scenarios signing identities and provisioning profiles are not displayed, even if they are installed and valid on the users machine. We will continue working on this issue, and expect to publish a fix into the Xamarin Alpha, Beta and Stable channels soon.

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.

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.
