There’s a great – but somewhat confusing – video up on Channel 9 covering the new Concurrency & Coordination Runtime – otherwise known as CCR (not to be confused with those ancient rockers!).  My definition: it lets you coordinate multiple threads and events without using nasty locks and semaphores and shared memory etc.

These guys are certainly passionate about it and it looks like one of those lovely little elegant libraries that makes you really happy to use.  One day soon I may actually need it.  Actually, I’ve been having problems with UI threading and async web service calls recently.  CCR makes this sort of coordination trivial.
