F# F# is a mature, open source, functional-first programming language for tackling programming problems with simple, maintainable and robust code. It is used in a wide range of application areas, particularly analytical components embedded in larger enterprise systems, and is available across multiple platforms. F# is a functional-first programming language which exploits functional programming in its core language and library constructs. The language includes the standard core tuple/list/option programming of typed functional languages, defaults to immutable data, has non-null data by default, includes type-inference in the Hindley Milner style, has monadic/monoidal syntax through “computation expressions”, has pattern matching, extensible through “active patterns”. The F# compiler is itself written in F#. Also see the F# Software Foundation’s Home Page.
