Target audience: .NET developers
Daniels’ comment: Actually it’s a while ago when I read this book. I mention it here because we are using it to educate developers which are new to C# 3.0 and the .NET 3.5 platform. The book is very well structured and gives a deep insight into the platform, language and the tools. It starts with the basic stuff (even object oriented approaches) and goes then deep into the darkest edges of the .NET platform. Only the chapters about WCF and WPF are a bit disappointing (too short).
