Just an FYI...

Versioning gets really complicated with Visual Studio 2008...

C# -- 3.0
VB -- 9.0
.NET Framework -- 3.5
ASP.NET -- 3.0

>I neglected to mention the version - sorry about that. I'm working with VS2005 right now, but it will be VS2008 and the 3.0 framework eventually (a section on linq would be ideal but if the book is the best as far as the version, then a separate book covering linq would be ok).
