For other uses, see C (disambiguation).
C# is a popular, general-purpose programming language developed for the Microsoft .NET Framework. C# is fully object orientated and is enjoying continuous improvement by Microsoft. C# programs are portable across all recent Microsoft operating systems since Windows 98 (but only partially on 98). C# programs consist of .exe or .dll files, each containing Common Intermediate Language (CIL) instructions, a manifest (table of contents), metadata, and (possibly) encapsulated resources such as images or audio.
To execute, C# program require the installation of the .NET Framework's Common Language Runtime (CLR), a virtual machine that hides any operating system details. The .NET CLR is available both for Windows client computers and Microsoft web servers.
