I recently got a copy of Advanced ASP.NET AJAX Server Controls For .NET Framework 3.5. This promises to be a great book. With .NET Framework 3.5, Ajax is really interesting the mainstream and the Ajax Server Controls make it very easy for the millions of ASP.NET developers to easily take advantage of the power Ajax offers.
This is the first book in the .NET Development Series to come out since I was asked to be on the editorial board for the series. It is great to get a chance to work with John Montgomery and Don Box. While the only pay I get for this gig is free books, I am excited to be able to help connect the industry experts on the most important technologies to the widest possible audience. If you do have title or author suggestions for the .NET Development Series, please let me know.
