Stable Release: Cycle 7

We are publishing the final builds for our next major feature release, called Cycle 7, to the Stable channel.

Please check out the product release notes to see all the fixes and known issues for this release, and use the below forum threads to report and monitor issues that may occur, as well as find any potential workarounds that may exist.

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. The functionality for this is supported in this release.

NOTE: Visual 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: The Cycle 7 version of Xamarin.VS requires Microsoft Build Tools 2015 (or Visual Studio 2015) to be installed. These tools can be downloaded from the Download tab of My.VisualStudio.com with a Visual Studio subscription or a Dev Essentials account.

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. These tools can be downloaded from the Download tab of My.VisualStudio.com with a Visual Studio subscription or a Dev Essentials account.


Known Issues

  • [Xamarin.VS]41836 – For iOS apps, breakpoints within async methods in PCL projects are not hit if the linker is enabled.
  • [Xamarin.VS/Xamarin.iOS] – Under certain conditions, downgrading from our Xamarin products in the Alpha channel to the Beta or Stable channel versions may result in the Xamarin.iOS plugin failing to load correctly.
    • Workaround – Delete the component cache  (steps here).
  • [Xamarin.VS & Xamarin.iOS] – When deploying WatchKit applications in Visual studio, the error “The file ‘bin\iPhoneSimulator\Debug\WatchKitApp1WatchKitApp.app\WatchKitApp1WatchKitApp’ does not exist” may appear.
  • [Xamarin.VS] – tvOS Applications built with the “Build ad-hoc IPA” checkbox enabled in “Debug/Release + Device” configuration will fail with the error “The ‘CopyFileToWindows’ task failed unexpectedly.”
  • [Xamarin Studio] –  41565 – “Could not load solution:” and “Load operation failed.” when attempting to open certain projects in Xamarin Studio 6.0.
    • Recommended fix – Open the problematic .csproj file in a text editor and remove the conflicting item from the <ProjectTypeGuids> element. For iOS extension projects, the most common fix is to remove the {FEACFBD2-3405-455C-9665-78FE426C6842}; item from the list.
  • [Xamarin.Android] – AOT+LLVM compiling is disabled in this release due to a crash discovered while trying to fix a compiler issue. It will be re-enabled in a future release.
