XNAViewer

How To Use

It works just like any other Control. Simply add it to your Toolbox and place it on your form.

The 4.0 .Net Framework also requires a runtime specification "App.config" file which can be copied from the example.

When your program is ready to start your game use the function ".RunGame(<your game here>);"
XNAViewer will do all the hard work for you!

Other self-explanatory functions are:
.PauseGame();
.ResumeGame();
.StopGame();
