I've got the following setup: The main application loads a XAP with an IPlugin implementation. The Plugin contains a 'DisplayPanel' that contains a referenced Control with other controls.

Now that I'm working on my newer application that uses MEF with the MVVM light toolkit, I've run into a case where I can't load specific plugins because they rely on a part that isn't getting exported.

Views can be created dynamically, say by selecting a menu item (somewhere). Newly created view would dispose of any old view looking at a ViewModel. Then it would make itself a current view of that ViewMod...

The plugins know about the viewmodel but the main shell UI will construct the view and bind the viewmodel using a convention over configuration type pattern. I have used some code from the Build-your-own-MVV...
I'm researching MEF as a solution to plug-in resolution in our existing .NET Application. In all of the examples that I can find, the main application creates an instance of the CompositionContainer and calls container.ComposeParts(this). The problem is, my application is not entirely built on MEF, so there is a hole in the object grap...
