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.

Alpha Release: Cycle 6 – 4th Alpha Preview

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. We wanted to release these builds to a wider audience for consumption via the Alpha channel.

As this is an Alpha release there are bound to be bugs. Please make sure to use the forums below to read up on issues as they are found, and see if any workarounds exist, or log a bug if one doesn’t exist already.


Important Notes

  • [Xamarin Studio / Xamarin.VS] – The Cycle 6 builds now require Xcode 7 or higher. For example, attempting to build an iOS app for device using Xcode 6.4 will now fail with “Native linking failed, undefined symbol:___divdc3”.
  • [Xamarin.VS] – Support for OS X 10.9 Mavericks has been deprecated. The Cycle 6 builds will now require OS X 10.10 Yosemite.

Known Issues

Preview: Android M Support – 3rd Preview

We are releasing our third preview with support for Google’s Android M SDK. This build supports the Android M Preview 3 released by Google on August 17th.

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