This is the third of another four part series on building cross-platform apps using Xamarin and C#. In this episode I am joined by James Montemagno, a developer evangelist at Xamarin. James takes us for a tour of CocosSharp, a Xamarin library for building 2D Windows, iOS and Android games from a shared C# code base. CocosSharp blends the power of the Cocos2D programming model with C# and the .NET Framework. James walks us through getting started with the Visual Studio templates and creating your first game.
