Among the most significant improvements to ASP.NET 2.0 are new server controls and services that make you dramatically more productive. In fact, when compared to its predecessor, ASP.NET 2.0 reduces the amount of code you have to write by about 75%. Creating interactive web applications has never been easier-but that still doesn't mean it's hassle-free! The difficulty in ASP.NET 2.0 is that it's so complete and flexible that there are many pieces that must be woven together to build a robust, scalable, and efficient application.

Fortunately, Programming ASP.NET, Third Edition is on the case, dispensing all the information you need to be effective with this dynamic tool. For starters, the book features a comprehensive tutorial on Web Forms, the user interface that gives web applications their look and feel. It then offers detailed explanations of all new controls, including web server controls, HTML controls, and custom controls. Used properly, these controls are able to take care of nearly all the foundation work-security, data access, layout, etc.-that you would normally have to write yourself. Free of these burdensome tasks, you can instead focus on your specific application.

Other new material found in this updated edition even shows you how to create ASP.NET 2.0 pages for mobile devices. With Programming ASP.NET, Third Edition at your side, there's virtually no end to the programming possibilities.

Written in part by veteran computer author Jesse Liberty, this book offers an excellent mix of coverage of important ASP.NET features that you will absolutely need to use for real-world programming. Readers with previous ASP experience will appreciate early sections that compare an older ASP sample with the new ASP.NET to highlight what's new and improved, with good explanation of the ASP.NET event model. The pace of this book is just excellent. The authors first move through the essentials, like basic ASP Web controls and data binding, before delving into data-driven applications using the (slightly complicated) ASP.NET database APIs. It also helps that the authors let you use Notepad (or another text editor) to create your ASP.NET programs first. (Later, they cover the details of Visual Studio .NET, pointing out how this tool can sometimes make it difficult to see where your code is generated.) There's also coverage of debugging and tracing techniques.

Standout sections on the calendar, Repeater, DataList, and DataGrid controls (all presented in good detail) will help you master these important controls. Coverage of techniques and support for validating user input in Web pages will also help you use these essential features.

The author's well-measured tutorial on Web services (much touted by Microsoft) is as good as any. Their demos (using a well-traveled example of a stock ticker server) will show you what all the fuss is about. They cut through the hype here and manage to show why Web services are a potentially better way toward distributed computing. Later sections look at deployment, configuration, and performance (as well as caching) options that you'll need to deploy and run your ASP.NET programs successfully. Coverage of security options in .NET rounds out the tour of what you'll need to create real applications.

Illustrated throughout with samples from VB .NET and C#, Programming ASP.NET is a worthy addition to the O'Reilly lineup and one of the best available titles for learning ASP.NET. The authors have achieved an excellent balance of practical, hands-on examples and essential programming techniques with the most important APIs and features, all without getting bogged down in the richness and complexity of .NET itself. --Richard Dragan
