OK, this may be a little off topic, but I think it's somwhat related to the release of the new Farseer engine...

How did you get the XNA Framework to operate with Silverlight? Or is it that MS MADE Silverlight capible of using the XNA Framework??

I ask because at the moment I am loving XNA GS, yet at work I have to use a horrible JAVA Web app to distribute 3D online applications. If I could build an XNA based solution and distribute it through Silverlight my world would be much better....

Thanks in advance for the various replys....

There was nothing XNA-specific in the Farseer engine except its use of Vector2 and Matrix, so we just implemented those data types in the Silverlight version ourselves. Everything else in the engine is 100% the same. The demo visualizer is completely redone for Silverlight, because graphics are so much different in it. I made it look the same, but the whole front end was a complete rewrite.

I originally built the engine to use the XNA math classes to avoid having to always map between XNA and some custom vector in Farseer.  That remains in the existing XNA version of the engine.  It makes things much cleaner to develop.

As Bill said, the Silverlight version just has it's own version of Vector2, Matrix... etc.

There is also a "QuickStartSample" project that I added last minute. It is a bare-bones XNA project that loads two RigidBodies and a RevoluteJoint between them.

I added this so people could see the basics of using Farseer without the clutter of the samples framework.

As for the samples framework. I tried to keep most the important logic contained in the Demo1, Demo2..DemoX classes so you should be able to just look at these to see how different things work.

I'll be adding to the docs over the next few days...weeks...months??
