Stable Release: Cycle 6 Final

We are releasing our final Cycle 6 to the Stable channel. These final builds contain all fixes from the previous releases, along with new feature and tons of improvements. Be sure to check out our blog post, and the product release notes below.

If you are used to the updater channels in Xamarin Studio and/or Visual Studio, simply switching to the Stable channel and getting the latest content will give you the final builds. We’ve also updated the standard installers, which will install the builds on your Mac and Windows machine if nothing has been previously installed. (Note – if you have gotten web previews of newer Xamarin Platform builds, the installer will not update and you should use the updater in the IDE against the Stable channel).

Mac Installer  |  Windows Installer

Please note, to use final builds to develop iOS applications in Visual Studio, you’ll need to install them 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 products, please log a bug report.

Alpha Release: Cycle 6 Preview Update – Release Candidate 1

We are releasing a updated preview of Cycle 6 to the Alpha channel. These updated RCs provide a slew of additional fixes on top of the previous builds, in addition to support for Xcode 7.1. There are still some issues remaining, but the quality is much improved since the initial RC, thanks in great part to community input. Thank you!

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 RC1 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 RC1 build on your Mac and Windows machine if nothing has been previously installed. (Note – if you have gotten web previews of newer Xamarin Platform builds, the installer will not update and you should use the updater in the IDE against the Alpha channel).

Mac Installer  |  Windows Installer

Please note, to use RC1 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 RC1 products, please log a bug report

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 

  • [Xamarin.VS] – Exception when opening interface.storyboard file for a WatchKit project in Visual Studio, when using Xcode7.
