Xamarin.Forms is a new library that enables you to build native UIs for iOS, Android and Windows Phone from a single, shared C# codebase. It provides more than 40 cross-platform controls and layouts which are mapped to native controls at runtime, which means that your user interfaces are fully native. Join Xamarin developer James Montemagno for an in-depth overview of Xamarin.Forms, and see how you can get started with Xamarin.Forms today.
