I am going to post the class files for the MXNA WebService App I put together over the weekend. I will post them as I add the comments.

I will eventually post all of the source, but I want to work out all of the kinks first.

The first class I am posting, MXNAAppController is the controller for the application. It handles all communication with the web services on the server, and contains a single view class, that contains most of the UI elements for the app.

So, if you find any bugs, or have any suggestions, post them in the comments.

Btw, big ups to Sean Voisen for the AS 2 support in his MovableType CodeBeautifier.
