CLR via C#

If you don't know Jeffrey Richter, you should. Read his books, his blogs, his MSDN articles. This book is a sample of what you need to know to program using the CLR. Especially (it's all good) well-written are the chapters on threading. If you manage software projects- you had better understand the chapters on threading. Everyone wants multi-processing, few know how to do it correctly. Anyone can make something difficult, Richter makes sense of the complex world of CLR. You need to read (study) this book.
