Physics Helper XAML allows you to easily create 2D physics based games and simulations for Windows 8, Windows Phone 7 and Silverlight 5 using C# or VB. It is a port of the Physics Helper
and uses the Farseer Physics Engine
. Why a Separate Version?
When I began porting the Physics Helper project to Windows 8, I realized that there were many breaking changes in WinRT and missing functionality such as Behaviors. It was much simpler to create a new version for Metro/WinRT and then port that new version to Windows Phone and other platforms. I think that the end result is much simpler and cleaner, as an added bonus!
