Sams Teach Yourself ASP.NET in 21 Days is the perfect book to introduce beginner and intermediate readers to the new technologies and frameworks presented by ASP.NET. By guiding readers through short but increasingly complex lessons, this book will give readers a strong foundation in ASP.NET, and the knowledge to develop their own creative solutions. Readers will delve into the new framework, the C# and Visual Basic programming languages, and techniques to approach difficult problems. The book will introduce the ASP.NET Framework, Visual Basic .NET, and C#, the new COM framework. The book will cover applications of these technologies.

This book is aimed at experienced ASP developers who are working at the leading edge, rather than the casual ASP developer or beginner. For example, we do not cover the basics of COM, ASP, or the programming languages we use in this book. You don't need to be experienced with ASP to make the most of this book although being relatively comfortable with ASP concepts with certainly help. This book is also ideal for Visual Basic developers who want to make the move into Web application design. You should also understand the general principles of the use of components, and have knowledge of Visual Basic (or VBScript). Some of the samples are written in other languages, such JScript and C#, but you don't need to be fluent in these languages to be able to use this book.

Professional Ajax discusses the range of request brokers (including the hidden frame technique, iframes, and XMLHttp) and explains when one should be used over another. You will also learn different Ajax techniques and patterns for executing client-server communication on your web site and in web applications. By the end of the book, you will have gained the practical knowledge necessary to implement your own Ajax solutions. In addition to a full chapter case study showing how to combine the book's Ajax techniques into an AjaxMail application, Professional Ajax uses many other examples to build hands-on Ajax experience.
