Silverlight 5 XNA and Blender

Silverlight 5 XNA and Blender. I have an issue that I dont know how to resolve.
I have exported materials via the OBJ export but I have no idea how to apply them using
the new Silverlight XNA code. I have no problem loading the objects into Silverlight but can not figure out how to apply the materials to the objects I loaded. I know its a long shot but I was wondering if anyone here has a clue on how to do this.
Thanks
