C# ( see SHARP) is a general-purpose high-level programming language supporting multiple paradigms. C# encompasses static typing,: 4  strong typing, lexically scoped, imperative, declarative, functional, generic,: 22  object-oriented (class-based), and component-oriented programming disciplines.The C# programming language was designed by Anders Hejlsberg from Microsoft in 2000 and was later approved as an international standard by Ecma (ECMA-334) in 2002 and ISO/IEC (ISO/IEC 23270 and 20619) in 2003. Microsoft introduced C# along with .NET Framework and Visual Studio, both of which were closed-source. At the time, Microsoft had no open-source products. Four years later, in 2004, a free and open-source project called Mono began, providing a cross-platform compiler and runtime environment for the C# programming language. A decade later, Microsoft released Visual Studio Code (code editor), Roslyn (compiler), and the unified .NET platform (software framework), all of which support C# and are free, open-source, and cross-platform. Mono also joined Microsoft but was not merged into .NET. As of November 2023, the most recent stable version of the language is C# 12.0, which was released in 2023 in .NET 8.0. Source: Wikipedia (en)
