Beta Preview 2: Cycle 8

We are releasing the second Beta preview of our next major feature release, called Cycle 8. As this is a Beta build, there are some known issues and the possibility of new issues being found during testing.

The issues addressed below are only the highest severity ones, so please check out the product release notes to see all the fixes and known issues for this preview.

The Xamarin team is looking for as much user feedback as possible on these Cycle 8 Beta versions, especially for the iOS 10 and Xcode 8 features. 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.

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.

Preview: Xamarin Profiler 0.34.0

Xamarin Profiler preview 0.34.0 is now available for download! There have been a number of fixes since our previous preview, which have been noted below.

Please note that the Mac app bundle has been renamed (from XamarinProfiler.Mac.app to “Xamarin Profiler.app”), so the old version needs to be removed before installing this new update, so that Xamarin Studio prompts the user for the new location.


Known Issues

  • No official support for profiling release builds is available at this time.
  • Data sets are correct at the time of collection, but data mining and representation is preliminary. This will improve in future releases.
  • Time instrument not available for Android and tvOS profiling.
  • Support for Xamarin.Mac app profiling is preliminary.
  • Installation on Windows with previous versions (>= 0.24) fails, so old profiler versions will be uninstalled first.

NOTE – These builds have been tested against Xcode beta 3 and beta 4. 

There is no target stable date final iOS 10 support at this time, as we have to wait until Apple finalizes and publishes their support before we can release ours. That being said, we may do additional preview releases between now and the final Apple release, so be sure to check back and see if newer versions become available in the coming months.

As with all our preview releases, this is not a product we officially support. If you encounter any issues, we recommend filing a bug in Bugzilla. You can also jump into the discussions on the forum thread posted below.

Stable Release: Cycle 7 Service Release 1

We are publishing a Stable release of our second bugfix release on top of Cycle 7, called Service Release 1.

NOTE Regarding .NET Standard and NuGet Client – These builds introduce compatibility with the new .NET Standard 1.6.  This in particular allows developers to consume NuGet packages that have been built against the .NET Standard 1.6.

NOTE: Since Google’s newest Android N previews now only allow linking to NDK-provided native libraries, existing apps using e.g. Mono.Data.Sqlite.dll will crash when running on Android N. You will need to rebuild your apps with Xamarin C6SR4, or later, to ensure that this crash does not occur once the final system image for Android N is released.

NOTEVisual F# Tools 4.0 RTM must be installed in order for F# console project builds to work with Cycle 7 Xamarin Studio build noted below.

NOTE: You will need to have Microsoft Build Tools 2015 installed in order to use the iOS Designer in the beta channel, with the current Xamarin.VS build.

NOTE: The Cycle 7 version of Xamarin Studio on Windows requires both Microsoft Build Tools 2013 (or Visual Studio 2013) and Microsoft Build Tools 2015 (or Visual Studio 2015) to be installed.
