Xamarin just pushed 3.9 to the stable channel. I’d recommend everyone doing Xamarin work update to this. The most important updates are:
- Support for creating 64-bit iOS apps. This uses the new "Xamarin.iOS Unified" profile. The existing profile has been deprecated but will remain for legacy enterprise-only apps. As of Feb 1, Apple will require new apps to be 64-bit and as of June 1, updates to existing apps must be 64-bit.
- See this guide for how to migrate existing iOS apps to the new framework. In most cases it’s just running the migrate tool and removing
MonoTouchfrom using statements.
- Support for Visual Studio 2015 Preview. For those of you using the VS 2015 preview, Xamarin 3.9 supports it.
- Visual Studio Android Emulator support. The VS Android emulator uses Hyper-V, so it’s fast and also works if you had to enable HyperV for any other reason and thus can’t use Genymotion or other ring 0-based virtualization.
