Introducing .NET provides a guide to the emerging set of technologies and standards that will be a part of the Microsoft .NET platform. Ideal for any programmer (or IT manager) who works with Windows, this title gives a worthwhile preview of a compelling set of technologies and of new ways to program for the Internet.
Apart from browsing the current .NET beta and documentation from Microsoft, it's somewhat difficult to find a way to understand all of the various aspects of .NET. The authors of this book have done the legwork for you and packaged their discoveries in a concise volume that examines numerous APIs and tools that developers will be using in the next year or so.
After a quick overview of .NET, the book looks at the Common Language Runtime (CLR), which allows different languages (like VB and C#) to interoperate on .NET. This focus is ideal for programmers who want to understand the future of programming. The book handily summarizes what the new C# language will offer, explaining in detail how Visual Basic 7 (now Visual Basic.NET) will differ from early versions of the language. In case you haven't seen the beta of the new Microsoft Visual Studio.NET, you get a tour of its features and interface. Other sections delve into the actual .NET classes you'll be using for development. (These APIs can be accessed from any programming language.) Material on the new Windows Forms and Web Forms shows the future of building user interfaces on the Windows platform. Other sections look at the new ASP.NET (for creating dynamic Web pages) and ADO.NET (for database programming).
Another compelling reason to read this book is its discussion of Web services, a potentially winning concept for a new generation of software. Using the Simple Object Access Protocol (SOAP), an XML standard for describing services, .NET programmers can call remote Web services almost as easily as local functions. The authors provide a remarkably simple example (which packages weather information on a custom Web page). Clearly, this is a core technology on .NET, and the book does a good job of explaining its potential.
Introducing .NET provides the blueprint for understanding what's to be included in the new .NET. Despite an understandable amount of "cheerleading" for Microsoft's new platform, this is good nuts-and-bolts information that's timely and just what developers need to understand the future of computing on Windows. --Richard Dragan

.NET is Microsoft's vision of "software as a service", a development environment in which you can build, create, and deploy your applications and the next generation of components, termed Web Services. All of Microsoft's major flagship products from Visual Studio to Windows and eventually Office are gradually being integrated into the vision and they will all offer services that will allow greater integration between products. .NET will allow developers to develop in whatever language they are comfortable with, via the introduction of a common language runtime, whilst at the same time provide "building block services" to ease application development.
Introducing .NET is designed to tell you exactly what you need to know, to cut through the fog and to bring you a clear picture of what .NET is, and what you can expect to be able to do using it.
