Welcome to Sams Teach Yourself ASP.NET in 21 Days, Second Edition! You most likely picked up this book because you're curious about building robust Internet applications. You've come to the right place! Throughout the next 21 days (and two bonus days), you'll examine every major aspect of Active Server Pages.NET, the Web-based programming framework from Microsoft: from how these pages look to how they are tied into the operating system.
ASP.NET is a technology that allows you to build and control dynamic Web pages easily. It is the next generation of Microsoft's Active Server Pages (which I'll refer to as classic ASP), and provides many enhancements to take advantage of new technology. With it, you can interact with databases, personalize Web pages for visitors, display pages on mobile devices (such as cell phones), and even build an entire e-commerce shopping site from scratch.
As you move through the tutorial-style lessons in this book, you'll discover just how easily these tasks can be accomplished. Not only will you see examples and learn how to build these and other applications, but you'll also gain the understanding to be confident in any endeavor you choose to pursue in ASP.NET.
This second edition is updated with the latest changes to the .NET Framework, and is completely compatible with the RTM version of .NET (build 3705 and higher). The examples and exercises have been updated as well. In addition, this edition more fully embraces C# with examples, discussion, and code.
