Be First To Try Our New Release Candidate

Miguel de Icaza

To keep pace with the rapid evolution of iOS, Android, and our own mobile innovations, we publish many updates to Xamarin over the course of the year. As Xamarin has grown, it has become increasingly important for our customers that every release of Xamarin be enterprise-grade: stable and high-quality.

Today, we are instituting a new release candidate process for all major updates to Xamarin. The goal of this process is to ensure that new versions of Xamarin do not introduce regressions. This also gives you an opportunity to try out our latest-and-greatest, and to ensure that it works for you and your team. We need your help to make this work!

This release candidate includes major upgrades to every major component of our platform. We have extensive new features available for everyone across the board: Android, iOS, Mac, Visual Studio, and Xamarin Studio, including a complete rewrite of our Visual Studio integration for iOS. We know you’ll love it.

New Visual Studio – iOS Support

Simplicity and Security

Building iOS applications from Visual Studio is now easier than ever! Rather than using the PIN-based Mac pairing process you may have you used in the past, the new Xamarin Mac Agent only requires that Remote Login is enabled on your Mac. That’s it—no additional setup or configuration is required.

The new connection manager in Visual Studio will discover, authenticate, and remember your Mac. Moreover, since all communication is tunneled securely through SSH, you only have to open one, well-known port (i.e., port 22) on your router or firewall. There’s no app to start on the Mac. If you have a compatible version of Xamarin.iOS installed, Visual Studio will automatically deploy and start the new Xamarin Mac Agent.

Improved Reliability

We redesigned the end-to-end communication between Visual Studio and your Mac with a focus on fault tolerance and recovery, eliminating the root of many sources of problems. This includes a spectrum of issues from debugging to deployment to disconnected agents: they’re all now magically accounted for.

Simultaneous Sessions

With the original build agent, only a single Visual Studio instance could be connected to the Mac. This made it frustratingly difficult to keep multiple iOS solutions open at once. The new iOS build experience allows multiple instances of Visual Studio to connect simultaneously.

Offline Support

We’ve made it easier to work without a connection to your Mac. Visual Studio will no longer prompt you to connect to your Mac unless you’re performing an operation for which the Mac is required, such as debugging or using the designer.

Android, iOS and Mac

You’ll be pleasantly surprised when you discover that we’ve replaced major components of our .NET runtime with the Microsoft’s open sourced stack, which brings many bug fixes and performance and compatibility benefits. More details are available on the Mono 4.2.0 release notes.

Getting This Release Candidate
