This book is written at a level where the reader needs to have a basic understanding of how ASP.NET works. It is not for someone who is completely new to ASP.NET. This book is lightweight and as such is easy to navigate. That being said, I would recommend against anyone reasonably experienced in ASP.NET buying this book. This is definitely a book for beginners. Someone just learning ASP.NET and getting ready to start presenting data using ASP.NET controls.
