Windows

  • Xamarin.VisualStudio_3.11.893.msi (dd3b114)

Mac

  • mono-android-5.1.6-5.pkg (9659226)

Reason for release: Additional bug fixes for the "Cycle 5" Stable Release on April 29 and the previous Cycle 5 Service Releases. (See the release blog for a short description of "Cycles" and "Service Releases.")

Date published: See https://releases.xamarin.com/.

NOTE: These "Beta" versions have to date only undergone the Alpha stages of the release process. A special exception has been made to publish these builds to the Beta channel rather than the Alpha channel so that the Cycle 6 Preview builds could be published to the Alpha channel. As usual, these "Beta" versions have not yet completed the full suite of tests by the Xamarin QA team, and customer reports of any regressions (or bugs that are incorrectly marked fixed) are still much appreciated, even if the problem would have eventually been caught during the full QA testing process.

Previous versions, downgrading

You can downgrade back to the current Stable version by switching updater channels.

Older versions (from before April 29)

If needed, you can downgrade back to older versions (from before April 29) by manually reinstalling each old package. See the "Previous versions, downgrading" section on the April 29 Stable release thread for the older downgrade links.

Guidelines for this thread

  1. This first post will be updated regularly.

  2. Hopefully this thread will help answer "what might break if I update to this release?"

  3. If you find a new problem that is specific to this version, please file a bug report.

  4. Please discuss older bugs that are unchanged in this release compared to the previous Stable version in Bugzilla instead.

  5. Of course for questions and discussions about topics other than bugs, feel free start new forum threads.

Fixes for known issues from recent release threads

  • Non-public Bug 30481, Bug 29557 - [Mono] [Android] [iOS] SqlConnection.GetSchema() fails with "SourceTable is required to be a non-empty string".

Remaining known issues from the April 29 Stable Channel release, with more common or severe issues near the top

  • Bug 30513 - [Android] The logged stack traces from exceptions thrown within async methods do not include the actual location where the exception was thrown. Partial workaround: switch back to the old Xamarin.Android 4.x exception propagation style by setting the XA_BROKEN_EXCEPTION_TRANSITIONS environment variable to true (see also Bug 30513, Comment 11).

  • Bug 30548 - [Android] Under certain conditions new threads take several seconds to start. This problem seems to be triggered by Xamarin.Insights 1.10. Partial workarounds: upgrade Xamarin.Insights to version 1.10.3, downgrade to version 1.9, or remove it entirely.

  • Bug 30915 - [Xamarin Studio] [Android] Xamarin Studio repeatedly asks for the password for the selected certificate when attempting to sign using SHA1withDSA certificates from keystore files. Xamarin Studio should instead display the error message from jarsigner: "private key algorithm is not compatible with signature algorithm" as it did in Xamarin Studio 5.8. (SHA1withRSA or MD5withRSA certificates do work without error.)

  • Bug 29731 - [Android] Android.Bluetooth.BluetoothAdapter.Enable is incorrectly marked as [Obsolete("deprecated")] for API level 20 and higher.

Remaining known issues from Cycle 5 – Service Release 2

  • Bug 31423 - [XamarinVS] [Android] [iOS] Locked .dll files: "Could not copy "... PortableClassLibrary1.dll" to "bin\Debug\PortableClassLibrary1.dll". Exceeded retry count of 10. Failed." This is a different problem than Bug 26841 because it affects .dll files rather than .dll.mdb files. It appears to be less common than Bug 26841. The results to date suggest that it is a bug in Visual Studio itself rather than in the Xamarin extensions. For example, it appears to be possible to hit the problem using a Windows Phone project, with no Xamarin involvement at all. The recent changes to the Xamarin "Clean project" process to properly remove stale files might have caused this to become easier to hit with Xamarin projects. In any case, it is still under investigation.
