I am currently reading another book on ASP.NET, Microsoft ASP.NET Step by Step by G. Andrew Duthie, published by Microsoft Press. I’m up to chapter 7 on configuring an ASP.NET application (using the web.config file).
Although I already know ASP.NET pretty well it is fairly complex so it doesn’t hurt to review the subject. Plus I am studying for the 70-305 Exam, Developing and Implementing Web Applications with Microsoft Visual Basic .NET and Microsoft Visual Studio .NET and rather than reread the study guide it is usually more helpful to read a secondary source of information to get additional details.
I have some other books on ASP.NET. One on security and one on web services. I also need to start learning ASP.NET 2.0 but I don’t have any books on that yet.
