Threading in C# by Albahari gratis
Advise: before attempting parallel programming – read up on the subject!
Normally we program by intellisense and the assumption that the name of the method does what we suppose it does. It can be thought of as lazy, that we don’t grok the framework before we start using it. But is does seem to work.
This is not the case with parallel programming. Do it without understanding it and you’re down the slippery slope.

Read up. The text is easy to read and well written.
I have read one other part (looking for interface and inheritance and virtual) of the first release and it was also good. If the rest of the book is as well written I suggest everyone to get a copy.
