F# is developed by the F# Software Foundation, Microsoft and open contributors. An open source, cross-platform compiler for F# is available from the F# Software Foundation. F# is also a fully supported language in Visual Studio and Xamarin Studio. Other tools supporting F# development include Mono, MonoDevelop, SharpDevelop, MBrace and WebSharper. Plugins supporting F# exist for a number of widely used editors, most notably the Ionide extension for Atom and Visual Studio Code, as well as integrations for other editors such as Vim, Emacs or Sublime Text.
