Could this be because we don't have a grid or canvas in the default template for
a window?  With our default templates I get this same experience (grey out, nothing
happens) for both 3rd party and normal WPF controls.  If I add a Canvas or a Grid
then I'm able to drag and drop controls onto the surface.

There's still issues at that point of not actually having the references added but
I think if I made sure the assemblies were deployable and did a clr.AddReference
then it'd work (we have plans to improve that).

So I think we just need to update the template to match the same sort of template 
that C# produces by default.
