>>I hooked Prism up to AvalonDock last weekend and created a basic framework/interface for my modules. MEF auto discovers the modules and they incorporate themselves into the menus and toolbars of the framework. So far it's been surprisingly easy to code and I like what I'm getting out of it.

Yep,it mimics the VS IDE quite well. Mostly like it because you can drag tabs out into windows or split the view so you can see more than one tab at a time.

The way I'm designing the modules, they won't be dependent on the host. I'm using services for the Menu,s Tool Bars etc. So the host could be almost anything as long as it loads the required services.
