DESCRIPTION
As the mobile landscape continues to expand and evolve managing multiple code bases in different programming languages and development tools can become a nightmare fast. In this session you will learn how to leverage the awesome features of C# and combine them with Xamarin technology to design and develop beautiful native cross platform mobile apps for iOS, Android, and Windows from a shared C# code base with the tools that you love. We will even see how to share more code with Xamarin.Forms, which enables you to build native UIs for iOS, Android and Windows Phone from a single, shared C# codebase.
