I'm almost done updating the XNA Control to beta 2. It mostly worked but had a few small changes based on API differences. One of the new features I added last night was that the XNA Control now implements the IGraphicsDeviceService, and IServiceProvider interfaces. I'm considering supporting GameComponents as well, but I don't want to guess at the internal implementation of how the components are handled and have it change under me (thus causing unanticipated behavior).
Once I get it done, I plan on putting up a page here with links to the source code, and also a binary distribution so you can just reference it and go.
