David Anson has put up a pretty cool application for looking at the default templates for Silverlight 2 controls. It works with Silverlight 2 RC0, which was released just this last week.
This is pretty freaking awesome stuff for anyone doing design in Silverlight. Go check it out.
A note: I would comment more about RC0 except that I’m doing alot of work with Silverlight that needs to be working with today’s plugins and it is my understanding that RC0 stuff may not work with the current plugin. If I’ve misunderstood, someone correct me please.
