OK I finally worked out what I was doing wrong with the 3D stuff. Basically XNA expects XNA specific compatible 3D resources and audio file to load correctly. Once that was established it works like a charm ( as seen below )




This rotating 3D model is very, and I mean very, easy to get working.

I've spoken to the people at RemObjects and they are keen to have these demos, and a few more, showing off Chrome's XNA and .NET 2.0 compatibility. They would like a game project template for XNA and they are speaking to Microsoft about what is required to get these Chrome created Exes working on an XBox 360.
