C# is a simple, modern, object oriented, and type-safe programming language derived from C and C . C# (pronounced “C sharp”) is firmly planted in the C and C family tree of languages, and will immediately be familiar to C and C programmers. C# aims to combine the high productivity of Visual Basic and the raw power of C . C# is provided as a part of Microsoft Visual Studio 7.0. In addition to C#, Visual Studio supports Visual Basic, Visual C , and the scripting languages VBScript and JScript. All of these languages provide access to the Next Generation Windows Services (NWGS) platform, which includes a common execution engine and a rich class library. The .NET software development kit defines a "Common Language Subset" (CLS), a sort of lingua franca that ensures seamless interoperability between CLS-compliant languages and class libraries. For C# developers, this means that even though C# is a new language, it has complete access to the same rich class libraries that are used by seasoned tools such as Visual Basic and Visual C . C# itself does not include a class library.
