In this session you will learn about the technology that Xamarin offers and how it works to enable developers to leverage a shared C# code base across all mobile platforms. I will walk you through developing, deploying, and optimizing your first mobile apps for iOS, Android, and Windows from a single code base. You will walk away with the knowledge to build cross platform mobile app with C# features such as LINQ, async/await, events, and delegates and inside of both Visual Studio and Xamarin Studio.
