Xamarin.Android Hotfix for Stable Channel to address “Could not load machine data” error

We are releasing an updated Xamarin.Android build to the Stable channel in order to address an issue with activation failures spotted in our recent Android M Stable Release from last week. This build is also being pushed to the Beta channel, as that channel shared the same Xamarin.Android version as the Stable channel at the time this issue was discovered.


Products Released

Preview: Xamarin Profiler 0.24

Xamarin Profiler preview 0.24 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.


Issues Addressed

  • 34605 – Profiler should now properly start and show graph/data on Mac.
  • 34160 – Error with ACTool not getting correct parameter for “IntermediateOutputPath” should no longer occur when building a project.
  • 34624 – The Stacktrace tab should now properly display in the Summary view for Instrument Allocations.
  • 34623 – Profiler should no longer crash when clicking on a row in the detail pan in Allocations List.
  • 32693 – Call tree visibility should now function properly when using the drill down feature multiple times.
  • 34627 – Stats should now properly update when clicking on the ‘Only Persistent Objects’ checkbox in the Allocations List view.
  • 34860 – Sorting on the Mac profiler should now work correctly.

Alpha Release: Cycle 6 – 5th Alpha Preview / Release Candidate 0

We are releasing a new preview of Cycle 6 to the Alpha channel. This series of builds will be the next major feature release of the Xamarin Platform when they release to Stable later this year. These builds are also the first Release Candidate we are publishing as part of a newly launched RC process, which you can read more about here.

If you are used to the updater channels in Xamarin Studio and/or Visual Studio, simply switching to the Alpha channel and getting the latest content will give you the RC0 series of builds. To make it as easy as possible for Xamarin developers to participate in this first RC, we’ve also prepared special versions of our installers which will install the new RC0 build on your Mac and Windows machine.

Mac Installer  |  Windows Installer

Please note, to use RC0 to develop iOS applications in Visual Studio, you’ll need to install the release on both your Mac and Windows workstations.

The biggest change with the Cycle 6 builds is an overhaul of how Xamarin builds iOS projects on your Mac from Visual Studio. If you happen to experience issues with any of the RC0 products, please log a bug report


Known Issues 

  • [Xamarin.VS] – Xamarin.VS fails to log into build server on Mac machines using El Capitan GM (beta 1). 
  • [Xamarin.VS] – Right clicking build host in XMA connection dialog does not successfully open context menu.
  • [Xamarin.VS] – Breakpoint positions sometimes change when debugging Android applications with multiple breakpoints.

Stable Release: Mono Framework for El Capitan

We are releasing an updated Mono Framework to the Stable channel. A bug has been identified as a critical issue affecting some internal tests, and we felt that releasing the fix was a priority.

The issue is caused by a new feature in El Capitan called System Integrity Protection (SIP). One of the changes resulting from SIP is that any environment variables prefixed with DYLD_* are blanked out when launching protected processes.   This caused problems for some applications, and in particular some features of Xamarin Studio.
