Developing Microsoft ASP.NET Server Controls and Components

"Forgot to mention Nikhil's book: Developing Microsoft ASP.NET Server Controls and Components. For those of you that don't know Nikhil wrote the ASP.NET data controls, was one of the principle dev leads for all of the ASP.NET controls, and is just a super star all around developer."

Sweet! ASP.NET Server Controls has to be one of the most practical features of the .NET framework. I'm sure there are developers out there who know how messy writing full blown web apps can get with a basic scripting language. ASP.NET provides a full blown OOP environment for developing sites with. Sounds like this book might be able to help out with extending that environment. I'm just surprised there are so few books covering this subject right now.
