Why is it so difficult to find common libraries in Prism v4 that were once present in v2. I want to use the "Microsoft.Practices.Composite.Presentation.Regions" namespace but I can't seem to find the equivalent in Prism v4. The same goes for the "Microsoft.Practices.Composite.Modularity" namespace.

As explained in this article from the Prism v4 MSDN documentation, the namespaces you're mentioning are now named Microsoft.Practices.Regions and Microsoft.Practices.Modularity.

From the documentation:

  • "The Composite and Composite.Presentation portions of the namespaces were removed and the Composite and Composite.Presentation assemblies collapsed into a single assembly named Microsoft.Practices.Prism.
  • The Microsoft.Practices.Prism libraries for Silverlight and WPF now register the Microsoft.Practices.Prism.Regions, Microsoft.Practices.Prism.Commands, and Microsoft.Practices.Prism.ViewModel namespaces with the xmlns definition."

I hope you find this helpful.
