Recently I came across Daniel Cazzulino's post about the CUA (Composite UI Application Block) they are working on
jointly with Microsoft. Now we know, Daniel, why you've been so quiet lately! I sense from Daniel's excitement about it that we are in for a very nice present!
Among the referenced links was one to the new "Patternshare" web.
Among others, Gregor Hoepke's work is mentioned. I've been reading his Enterprise Patterns book off and on and it has been a real eye-opener. This Patternshare site is well-organized and has lots of friendly features.
