Programming C# Jesse Liberty Publisher: O'Reilly First Edition July 2001 ISBN: 0-596-00117-7, 680 pages The goal of C# is to serve as a high-performance language for .NET development—one that is simple, safe, object-oriented, and Internet-centric. Programming C# teaches this new language in a way that experienced programmers will appreciate—by grounding its application firmly in the context of Microsoft's .NET platform and the development of desktop and Internet applications. 2 Programming C# 3 Preface 11 About This Book 11 How the Book Is Organized 11 Who This Book Is For 13 C# Versus Visual Basic .NET 13 C# Versus Java 14 C# versus C++ 14 Conventions Used in This Book 14 Support 15 We'd Like to Hear from You 15 Acknowledgements 16 Part I: The C# Language 17 Chapter 1.
