Summary

The definitive reference to the C# Programming Language, updated for the new version 4.0, direct from its creator, Anders Hejlsberg

New to this edition - all code presented in full color.

Contains insightful, valuable annotations from twelve leading C# programmers, available nowhere else.

C# has become the most widely used language for Windows development.

Anders Hejlsberg is the creator of C#, and a true legend among programmers. C# is now firmly established as the most-used language when writing applications for Windows and the Microsoft platform.

Written by the language's architect, Anders Hejlsberg, and design team members, and now updated for C# 4.0, The C# Programming Language, 4/e, is the definitive technical reference for C#. It provides the most complete specification of the languages, along with descriptions, reference materials, and code samples from the C# design team.

This edition also adds valuable notes, comments, and tips from twelve of the world's top C# programmers, including Bill Wagner, Chris Sells, Jesse Liberty, and Brad Abrams. It has been brought fully up to date with the new features of C# 4.0. And new to this edition, all the code will be presented in full color, so that it appears in the book exactly as it appears on screen. This book is a must-have for any developer using C# on a regular basis.

“Based on my own experience, I can safely say that every .NET developer who reads this will have at least one ‘aha’ moment and will be a better developer for it.”-From the Foreword by Don Box

Author Biography

Anders Hejlsberg is a programming legend. He is the architect of the C# language and a Microsoft Technical Fellow. He joined Microsoft Corporation in 1996, following a thirteen-year career at Borland, where he was the chief architect of Delphi and Turbo Pascal.

 

Mads Torgersen is the Program Manager for the C# language at Microsoft, where he runs the day-to-day language design process and maintains the language specification.

 

Scott Wiltamuth is Director of Program Management for the Visual Studio Professional team at Microsoft Corporation. At Microsoft, he has worked on a wide range of development tools, including OLE Automation, Visual Basic, Visual Basic for Applications, VBScript, JScript, Visual J++, and Visual C#.

 

Peter Golde was the lead developer of the original Microsoft C# compiler. As the primary Microsoft representative on the ECMA committee that standardized C#, he led the implementation of the compiler and worked on the language design. He is currently an architect at Microsoft working on compilers.
