It is official; we've successfully run Pong under Mono.Xna! It is running with either the Microsoft or mono runtimes!
Last night, I completed most of the core functionality within the Microsoft.Xna.Framework.Game.dll assembly, and wrote a number of unit tests to exercise the Game logic.
Looks and runs identical to it's counterpart running under the Microsoft implementation of Xna.
My next step is to run it under the mono runtime on my windows machine and then follow with running it on my MacBook Pro. This is completed. Now for my Macbook Pro.
I will submit patches after I complete the additional classes I stubbed to get this basically working.
