In a Nutshell (O'Reilly): ASP.NET in a Nutshell (PDF)

ASP.NET in a Nutshell is a concise, one-volume reference to everything you need to make effective use of ASP.NET.

Updated for Visual Studio .NET 2003, the 2nd edition of this book includes fresh information on application and web service development, custom controls, data access, security, deployment, and error handling, new material on web application development for mobile devices, plus an overview of the class libraries.

Configuration settings in web.config are also documented
A Quick Reference to the types (the classes, structures, interfaces, delegates, events, and enumerations) found in web-related namespaces to the .NET Framework Class Library.
