Beta Preview: Cycle 6 Preview Update – Release Candidate 3

We are releasing a slightly updated preview of Cycle 6 to the Beta channel. These updated RCs fix a known issue with Xamarin Inspector compatibility from RC2. The Xamarin.Android, Xamarin.Mac, and Mono Framework remain unchanged from the previous release.

If you are used to the updater channels in Xamarin Studio and/or Visual Studio, simply switching to the Beta channel and getting the latest content will give you the RC3 series of builds. To make it as easy as possible for Xamarin developers to participate in this RC, we’ve also prepared special versions of our installers which will install the new RC3 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 Beta channel).

Mac Installer  |  Windows Installer

Please note, to use RC3 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 RC3 products, please log a bug report.


Known Issues

  • [Xamarin Studio] – Holding down Command+Z batches undo actions. (Undo is not executed until key combination is released.)

Watchkit / WatchOS 1 Hotfix Technical Bulletin

We are aware of an issue with our current Xamarin.iOS build that may prevent submission of watchOS 1 apps built using WatchKit. We are working on a hotfix for this issue, and hope to have updated builds for both Xamarin Studio and Visual Studio out later this week.

In the interim, we are making available a preview build of an updated Xamarin.iOS that is compatible with the current Xamarin Studio stable build that should address this issue. This preview is not compatible with Xamarin.VS, but the upcoming Stable hotfix should address this for everyone, including VS users.


Known Issues

[Xamarin.VS / Xamarin.iOS] – watchOS 1 apps built with WatchKit will be rejected during submission with the notification “Invalid WatchKit Support”.

Preview: Xamarin Inspector 0.3.1.1

We are releasing our first preview of a brand new tool, the Xamarin Inspector for iOS, Android, Mac, and WPF applications. Xamarin Inspector is an interactive tool that you can use to diagnose and prototype changes in your application. The inspector can attach to a live application on any of the supported platforms. Read more about this new tool on our main blog.

The Xamarin Inspector is available on both Windows with Visual Studio and on Mac OS X with Xamarin Studio. To use the Inspector, you’ll need to use our Release Candidate. Once you have the RC installed, you can download the Inspector from the links below, or from the supporting documentation page.

This is an early preview of the Xamarin Inspector, and we need your feedback to improve it and make it as awesome as possible. You can help out in this effort by reporting any issues you experience while using the Xamarin Inspector preview.

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

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.
