Sams Teach Yourself: ASP.NET Ajax

This book served as a good introduction and overview of what is included in ASP.NET Ajax but if you’re looking for a deep dive look elsewhere.

I would definitely recommend this to anyone that has never used ASP.NET Ajax or that has used an older version. This book will get you up to speed on the basics and introduce you to the Javascript library. Developers that have used ASP.NET Ajax before will need to look elsewhere for a satisfactory read though.
