Here's an interesting post by Hammett, the leader of the Castle Project and writer of the Monorail MVC framework. He was invited up to Redmond to play with the MS MVC Framework. His attitude is very mature; he says that he won't bother with Monorail 2.0 if everything he wants from an MVC framework is supplied by MS. There's obviously a great deal of mutual respect going on. I wonder how long before Hammett's working for The Beast?
