Interesting videos on channel 9

First one explains what ADO.NET entity framework is and it is really good because Charles asked a few hard/interesting questions. Second one is about CCR (Concurrency and Coordination Runtime) where Jeffrey Richter and George Chrysanthakopoulos present the new incarnation of the runtime. They haven't changed the internals of it they've just improved public API. Well they think they've done it. I still think that they are far from perfect. If the main class that is used in nearly every statement is a static one then something is wrong.
