1/3 a quick round up of things a developer should know about, unit tests, source code control, extreme programming. 1/3 a catalogue of .Net c# utilities 1/3 a "missing manual" of Visual studio tweaks. The developer material will not be new to anyone who reads joelonsoftware or any other programmer groups. You will still need to read the real books on these topics to get any use. It's very .Net + c# specific and will date quickly as the tools mentioned disappear / change. May be useful if you are new to Visual Studio or you have only read the "learning X in N days" type books and you need to bluff about software engineering topics.
