Alpha Release: 15.2 Alpha Preview 3

We are releasing the third Alpha preview of our next major release, called 15.2. This release includes our next preview of Visual Studio for Mac.

Using the latest Visual Studio for Mac Preview 8 with this release is encouraged, but you can also continue to use Xamarin Studio if you prefer (though new previews of XS are not included in this release). If you are updating from Visual Studio for Mac Preview 5 or earlier, you’ll need to check for updates once to install the new Preview and then once more to get the new Xamarin Platform components.

New: This Xamarin release is now also available in Visual Studio 2017 Preview as part of the April 20 update (26419.01 – Preview).

As this is an Alpha build, there are some known issues and the possibility of new issues being found during testing. Of course, additional bug reports are still welcome for these preview versions. If you see any suspicious behavior that you wish to report, please file a quick bug.

If you notice an error in this blog post or have trouble downloading one of the installer packages, please let us know in the corresponding forum thread.

Please check out the product release notes to see all the fixes and known issues for this release.


Products Released


Installing the Alpha and switching back to Stable

You can install this new Alpha version or switch back to the current Stable version by changing updater channels.


Upcoming Release Dates

Alpha 1 – April 6th 2017

Alpha 2 – April 11th 2017

Alpha 3 – This Release!

Preview 7: Visual Studio for Mac

We are releasing our seventh preview of Visual Studio for Mac. Visual Studio for Mac is an evolution of Xamarin Studio, and includes all the functionality of Xamarin Studio 6.3.

If you already have VS for Mac installed, this update will appear in the Alpha updater channel within the IDE. If you do not yet have a VS for Mac Preview, you can download this newer one here. Future updates will then be available to you through the VS for Mac “Check for Updates” menu option.

Please note that the VS for Mac IDE has its own set of updater channels, separate from Xamarin Studio and Xamarin.VS. As of Preview 6 and for all future Preview releases of VS for Mac, only an Alpha channel will appear. That channel provides the latest preview updates as they become available. When VS for Mac moves out of preview status, the available updater channels will be adjusted accordingly. It should be noted that since VS for Mac is still in preview, it is not yet a fully supported product.

Visual Studio for Mac can be installed side-by-side with Xamarin Studio.


 

Known Issues

54993 – “The root assembly … conflicts with another assembly” build error will appear for Xamarin.iOS projects in Xamarin.VisualStudio 4.4.0 on Windows due to the incompatible Xamarin.iOS 10.10.0 Alpha version that is installed on the Mac by the latest Visual Studio for Mac Preview.

  • Visual Studio 2015 and 2013 users can optionally update to the Alpha updater channel to get the compatible Xamarin.VisualStudio 4.5.0 Alpha version. For VS 2017 users and users who do not wish to use the Alpha versions on Windows, please refer to the bug report for a few other options for how to resolve this issue.

Alpha Release: 15.2 Alpha Preview 2

We are releasing the second Alpha preview of our next major release, called 15.2.

Using the latest Visual Studio for Mac Preview 7 with this release is encouraged, but you can also continue to use Xamarin Studio if you prefer (though new previews of XS are not included in this release). If you are updating from Visual Studio for Mac Preview 5 or earlier, you’ll need to check for updates once to install the new Preview and then once more to get the new Xamarin Platform components.

Note that this preview version is not yet available in Visual Studio 2017. This post will be updated within the next couple of days with the steps to try this release in Visual Studio 2017.  Edit: Unfortunately some new complications came up with the packaging process for Visual Studio 2017. Work is underway to resolve those issues, but in the mean time, if you use Xamarin.iOS in Visual Studio 2017, be sure to hold off for now on trying the preview versions on the Mac. (Otherwise you will run into some incompatibility errors such as “The root assembly … conflicts with another assembly”.) The Visual Studio Preview version 15.2 (26412.01) from April 17 does not yet include the Xamarin 15.2 Alpha preview component.

As this is an Alpha build, there are some known issues and the possibility of new issues being found during testing. Of course, additional bug reports are still welcome for these preview versions. If you see any suspicious behavior that you wish to report, please file a quick bug.

Alpha Release: 15.2 Alpha Preview 1

We are releasing the first Alpha preview of our next major release, called 15.2.

This initial Alpha release currently only includes updates for Mac and is not compatible with the existing Stable Xamarin version in Visual Studio on Windows. So for the moment please only try this Alpha version if you do all your development work on Mac. Keep an eye on this post for updates about the corresponding Windows updates soon.

Using the latest Visual Studio for Mac Preview 6 with this release is encouraged, but you can also continue to use Xamarin Studio if you prefer. If you are updating an earlier Visual Studio for Mac Preview, you’ll need to check for updates once to install Preview 6 and then once more to get the new Xamarin Platform components.

As this is an Alpha build, there are some known issues and the possibility of new issues being found during testing. Of course, additional bug reports are still welcome for these preview versions. If you see any suspicious behavior that you wish to report, please file a quick bug.

If you notice an error in this blog post or have trouble downloading one of the installer packages, please let us know in the corresponding forum thread.
