Contents | Index Microsoft's NET is revolutionizing Windows-based software development Since its initial release in 2002, NET has changed significantly, becoming the foundation for a new generation of Windows applications The NET Framework and Visual Studio, the two core aspects of this initiative, provide a multilanguage environment in which developers can create Web services, graphical user interfaces, and other kinds of applications Taken as a whole, the NET technologies have changed the way nearly every Windows application is built Now fully updated for version 2.0 of the NET Framework and Visual Basic 2005, Understanding NET, Second Edition, is a concise guide to the landscape of Windows development Margin notes, detailed diagrams, and lucid writing make this book easy to read and navigate, while analysis sections explore controversial issues and address common concerns David Chappell's independent perspective and straightforward descriptions clarify both how the NET technologies work and how they can be used Coverage includes An overview of NET and its goals The Common Language Runtime (CLR) The NET languages, including C#, Visual Basic, and C++ The NET Framework class library Building Web Applications with ASP.NET Accessing Data with ADO.NET NET framework integration with SQL Server 2005 The key to using a new technology is to understand the fundamentals This book provides the robust foundation developers and technical managers need to make the right decisions and maximize the potential of this revolutionary framework Understanding NET, Second Edition By

David Chappell's Understanding NET, Second Edition "David Chappell's Understanding NET, Second Edition, contains excellent coverage of the CLR, class library, ASP.NET, ADO.NET, and distributed applications It is still the best technical overview of NET to date, and I recommend it to anyone making the transition to NET." Dave Corun Director of Microsoft Technologies Catalyst IT Services "David's coverage of all things NET is extensive and thorough Even regular users of Visual Studio will learn something about NET that they didn't know." Harry Pierson Architecture Strategy Team Microsoft Corporation "Understanding NET, Second Edition, will give managers the knowledge and vocabulary they need to communicate with their developers Developers looking to obtain a highlevel view of the NET Framework before going into each topic in depth will also benefit from this book This book helps developers get a bird's-eye view of NET Framework before they engage in the long learning curve required This book is very well organized and technically accurate." Cesar Bermudez MCAD, MCSD, MCDBA, MCSA, MCSE, MCTS, MCT, A+, iNet+, CIW President DotNet Architects, Inc "David Chappell has an astute understanding of Microsoft technology and an ability to explain complex systems in a way that is both enticing and thoroughly educational The second edition of his book, Understanding NET, shows that he remains one of the best technology authors in the business." Richard Monson-Haefel Author and Senior Industry Analyst Burton Group Independent Technology Guides David Chappell, Series Editor The Independent Technology Guides offer serious technical descriptions of important new software technologies of interest to enterprise developers and technical managers These books focus on how that technology works and what it can be used for, taking an independent perspective rather than reflecting the position of any particular vendor These are ideal first books for developers with a wide range of backgrounds, the perfect place to begin mastering a new area and laying a solid foundation for further study They also go into enough depth to enable technical managers to make good decisions without delving too deeply into implementation details The books in this series cover a broad range of topics, from networking protocols to development platforms, and are written by experts in the field They have a fresh design created to make learning a new technology easier All titles in the series are guided by the principle that, in order to use a technology well, you must first understand how and why that technology works Titles in the Series Brian
