The professional programmer’s Deitel® guide to C# and the powerful Microsoft® .NET Framework

Written for programmers with a background in C++, Java or other high-level languages, this book applies the Deitel signature live-code approach to teaching programming and explores Microsoft’s C# language and .NET Framework 3.5 in depth. The book is updated for Visual Studio® 2008 and C# 3.0, and presents C# concepts in the context of fully tested programs, complete with syntax shading, code highlighting, line-by-line code descriptions, and program outputs. The book features 200+ C# applications with about 20,000 lines of proven C# code, and hundreds of tips that will help you build robust applications.

Start with a concise introduction to C# using an early classes and objects approach, then rapidly move on to more advanced topics, including the .NET Framework 3.5, LINQ, WPF, ASP.NET AJAX, WCF web services and Silverlight™. You’ll enjoy the Deitels’ classic treatment of object-oriented programming and the OOD/UML™ ATM case study, including a complete C# implementation. When you’re finished, you’ll have everything you need to build next-generation Windows applications, web applications and web services.

TheDeitel® Developer Series isdesigned for practicing programmers. The series presents focused treatments of emerging technologies, including .NET, Java™, web services, Internet and web development, and more.
