This section provides detailed information on key C# language features and features accessible to C# through the .NET Framework.

Most of this section assumes that you already know something about C# and general programming concepts. If you are a complete beginner with programming or with C#, you might want to visit the Introduction to C# Tutorials or Getting Started with C# interactive tutorial, where no prior programming knowledge is required.

For information about specific keywords, operators and preprocessor directives, see C# Reference. For information about the C# Language Specification, see C# Language Specification.
