C#, pronounced like the musical note with the same name, is a language developed by Microsoft and was first released in 2000 as a part of the company’s .NET initiative. The language was designed by Anders Hejlsberg, a Danish software engineer, who first called it Cool (for C-like Object-Oriented Language). Microsoft renamed it before its first official release for copyright reasons.

The language is designed to be a simple, modern, and object-oriented programming language. The language is primarily used within Microsoft’s .NET Framework.

Note that all noncompound statements in C# end with a semicolon.
