Movement/control with Farseer Physics Engine 1.0.0.5 (Silverlight 2 beta 1)
In this sample you learn one way to capture keyboard inputs, react on them by applying force to an object and that way control the object in the game. Again this sample is a simplified version of the code from the original Farseer Physics Engine demo code.
