This book will provide the definitive resource for ASP.NET developers working in C#, not just to the features of ASP.NET but also how to use them best. Fritz Onion looks at working examples of how Web applications are built today, and then looks at what ASP.NET offers to simplify constructing Web applications of this type. In addition to explaining how to use ASP.NET and examining why it is built the way it is, Onion also explores implementation tools not covered in any other books. He helps the reader acquire a broader understanding of the technology and how it fits in with other tools. From his experience teaching ASP.NET to working developers, Onion knows what information they need, what questions they have, and how to organize and present the material in the best way possible. As Justin Burtch, a Software Engineer at Integrated Data Systems expressed it, "This book does not try to be everything to everyone. As a result, it is able to provide both breadth and depth on the subject. Essential ASP.NET is positioned to become the seminal book on the most important advancement to web development in years."
