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.

Beta Release: Cycle 5 – Service Release 4

We are releasing the Cycle 5 Service Release 4 builds to the Beta channel. Normally these builds would go to the Alpha channel first, but as we are using that for an advance preview of our next major feature release, we’re moving the Cycle 5 Service Release 4 builds to Beta directly. There will likely be one or more updates to these Beta builds before they go to Stable, so this isn’t cutting the timeframe for this release short.

As this is an earlier than normal Beta, there will probably be some issues that still need to be fixed, and others we may find as time goes on. Please use the below forum threads to report and monitor issues that may occur, and find any potential workarounds that may exist. 

** Note for Xamarin VS 2015 Users – If you installed Xamarin using our integration with Visual Studio 2015, you may be prompted to upgrade multiple times due to this release. Users installing with that method were placed on the Alpha channel by default, and we’ve made a one-time adjustment to set you back to the Stable channel. This will result in one upgrade to the new Alpha, and one update to the latest Stable release. Please feel free to select the updater channel you’d like to use, outlined in this guide.  **

Alpha Release: Cycle 6

We are releasing a preview of a future stable release, dubbed Cycle 6 to the Alpha channel. This series of builds will be the next major feature release of the Xamarin Platform when these builds release to Stable later this year. We wanted to release these build to a wider audience for consumption via the Alpha channel. If you are looking for the iOS 9 preview, you can find that here.

As this is the first Alpha release of a major feature update, 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. Additionally, please note that this first release does not have a compatible Xamarin.VS build, thus there will be a temporary break between Xamarin.VS and Xamarin.iOS if you are on the Alpha channel. We are working to fix a blocking issue with the Xamairn.VS product, and should be doing an updated Alpha build for that very soon.


Known Issues 

  • [Xamarin Studio] – Xamarin Studio Windows build is not available with this release. This will be provided during the next Cycle 6 Alpha update.
  • [Xamarin.VS] – Xamarin.VS will be incompatible with Xamarin.iOS 8.13.0 for the time being. We will be putting out an updated VS to the Alpha channel soon which will restore compatibility.

** UPDATE – The Xamairn.iOS build now also includes a fix for Watch Apps being rejected during app submission. **

We are releasing an updated preview of our next upcoming stable release, dubbed Cycle 5 – Service Release 3, to the Beta channel. These builds contain additional patches that were not included in the previous alphas.

This Beta release is almost ready for Stable, however we are waiting on a fix for one remaining issue, noted below. If you are encountering this issue and need to submit a Watch App immediately, we provided a download only build of Xamarin.iOS last week, based off our current Stable build to address this issue. This will be fixed for Cycle 5 Service Release 3 when it goes to Stable.
