F# (pronounced F sharp) is a general-purpose, high-level, strongly typed, multi-paradigm programming language that encompasses functional, imperative, and object-oriented programming methods. It is most often used as a cross-platform Common Language Infrastructure (CLI) language on .NET, but can also generate JavaScript[7] and graphics processing unit (GPU) code.[8]

F# is developed by the F# Software Foundation,[9] Microsoft and open contributors. An open source, cross-platform compiler for F# is available from the F# Software Foundation.[10] F# is a fully supported language in Visual Studio[11] and JetBrains Rider.[12] Plug-ins supporting F# exist for many widely used editors including Visual Studio Code, Vim, and Emacs.

F# is a member of the ML language family and originated as a .NET Framework implementation of a core of the programming language OCaml.[4][5] It has also been influenced by C#, Python, Haskell,[3] Scala and Erlang.
