What is your favorite ASP.NET Book ?

I’m  working on adding a books recommendation section to the ASP.NET forums.

I’ll only be recommending books that I’ve actually been able to review myself, since I really want the value of the recommendations to be very high and topically specific.

If you have a favorite book about any specific ASP.NET (or related topic like IIS) please let me know. (Use the contact form and tell me the Title and Author).

I’ll get a copy of the book myself and if I agree, I’ll add it to the list of recommendations!
