New Post: How do you use this with Prism?

I can't seem to find a way to use this with Prism without having to use:

using System.ComponentModel.Composition;
using System.ComponentModel.Composition.Hosting;

..to create my AggregateCatalog, my goal to mirror my Windows, Phone and Desktop app's using MEF2. So far I only can find examples using a Console app. Where can I find one using MEF2 in Windows, Phone or Desktop?

Thanks!...
