Finally got my hands on Dino Esposito's book Introducing Microsoft ASP.NET 2.0. The term "finally" has a special meaning for me: I was the technical editor on this book, and quite a lot of work went into this book project, because writing such a book isn't done in a day, and ASP.NET 2.0 was/is a moving target. So even with the most stringent editing, there inevitably will be some "mistakes" caused by changes.
In the Acknowledgements, Dino writes "Christoph Wille, who reviewed the contents from a technical perspective, was one of the most attentive and insightful reviewers I have ever had (and I have written quite a few books)." He has a gift for words - a royal pain in the posterior would be the tagline I'd choose for myself.
