About a month ago I posted some ideas around MEF and Prism together. As part of the post, I presented 2 high-level scenarios for MEF/Prism integration (and there are likely more)
Recently Jeremy Likeness of Wintillect started exploring the first approach. He’s started a series of blog posts on his explorations down that path. If you check the series you’ll see how he is introducing a new type of module called a PartModule that then uses MEF. The approach he takes is nice because it uses all of the existing Prism module loading infrastructure including Unity, and then adds on that when the module is received, it is registered through MEF. He also leverages MEF’s recomposition capabilities such that when new things are received, they automatically show up as recomposable parts are recomposed.
Jeremy has 3 posts in the series so far, the content is nice and it includes all the code.
This is just one of what I am sure will be many explorations to come!
