C# has become one of the most prolific languages used in game development. Games developed in C# can be created to target desktops, tablets, mobile devices and game consoles, while sharing nearly the entire code base. On mobile devices 2D games in particular are massively popular. In this session, we'll explore how to use C# in conjunction with Microsoft and Xamarin to develop 2D games that will work on iOS, Android and Windows platforms. We'll cover the basics of 2D game development, working with multiple scenes, animation and even physics. By the end of the session, you'll have seen how to make a cross-platform 2D game that you can use as the basis for creating your own games.
