One Team – 4 Books on ASP.NET 3.5
I just released Learning ASP.NET 3.5 which is very exciting, through I must
quickly and freely admit that my co-authors did a fantastic job shouldering the bulk of the task of the massive re-write to bring this book fully up to date for ASP.NET 3.5.
The Learning series is O’Reilly’s on-ramp, while the Programming books are targeted at the more experienced and professional programmer. That said, this book is surprisingly comprehensive and we’re quite 
proud of it.
There are quite a few good books on ASP.NET 3.5, one written by my colleague Scott Hanselman, that has gotten rave reviews.
Then there’s ASP.NET 3.5 Unleashed by Stephen Walther, new to our team but not new to writing fantastic books on ASP.NeT
Oh yes, I almost forgot, I’m about to release Programming ASP.NET 3.5, due out 
Sept. 15.
I suspect there are even some books by people not on our team.
So don’t buy anything until you read through a few books and decide on what you like in terms of style, coverage, approach, exercises and all those intangibles that make for a great technical book.
Enjoy.
