Over the last year Joel Rumerman and I have been working on a book for Addison-Wesley that is part of the Microsoft’s .NET Development Series that Addison-Wesley publishes. It has been a long haul but the fruits of our labor are starting to take hold. The book is entitled Essential ASP.NET Ajax Controls and covers both the JavaScript and .NET side of creating controls in ASP.NET Ajax and the Ajax Control Toolkit. The book has been a blast to write and we hope you will enjoy it. The topic is something Joel and I have been involved with since the early Alpha as part of the ATLAS First Access program that began in early 2006.
