What's New in this Release

Notable Changes

Shell

This release introduces preview support for UWP thanks in large part to the contributions of Morten Nielsen. With the initial implementation in, smaller pull requests can now be made to complete missing functionality and stabilize it. To use Shell in your UWP application, you'll want to add a UWP project with Xamarin.Forms if you don't already have one, and then initialize the feature in your UWP App.xaml.cs:

global::Xamarin.Forms.Forms.SetFlags("Shell_UWP_Experimental");
Xamarin.Forms.Forms.Init(e);
