Mission Statement

The mission of the F# Software Foundation is to promote, protect, and advance the F# programming language, and to support and facilitate the growth of a diverse and international community of F# programmers.

The F# Software Foundation (FSSF):

  • Maintains a core open-source F# code repository and distributions made available to the public free of charge for use across multiple platforms. This includes the F# compiler, F# language specification, the F# core library and assorted tools and applications.
  • Solicits and manages contributions to this open source F# codebase, and may perform these services on behalf of other open source F#-related codebases. Contributions to the open source F# codebase will maintain the integrity of the F# language and will initially focus on broadening the reach of F# across multiple platforms rather than extending the functionality of the F# language (see notes below).
  • Owns resources relating to F# including
  • Maintains the fsharp.org domain as:
    • A website which gives authoritative and up-to-date information about how to get, use and contribute to F# across a diverse range of platforms; links to other F# news, community, Q&A, social, user group and educational; gives clear and helpful links to commercial companies, tools and products that relate to F#; and hosts other content consistent with the mission statement of the FSSF
    • The email addresses …@fsharp.org for the use of the foundation
  • Seeks to:
    • expand the relevance and importance of F# skills and knowledge
    • expand the range of technologies which can interoperate with F#
    • expand the range of platforms where F# can be used
    • encourage a broad and diverse range of contributors to F#, including commercial, open source and educational contributors
    • publicize and promote the adoption of F#
    • facilitate the ongoing development of F#-related technology and educational resources, including contributing to F# conferences


  • The FSSF acknowledge the role of Microsoft as the current primary developers of the F# language, open-source compiler and open-source core tools, with a focus on the Windows platform. They accept that as an excellent ongoing arrangement. They welcome Microsoft’s contributions to the aims of the FSSF through both the open source releases of the F# compiler and the commercial releases of the Visual F# tooling.
  • The word “owns” in the text above currently means that the relevant property is either owned by the FSSF or one core member owns the relevant property and has agreed to dedicate it to the use of the organization and transfer it to the FSSF at a future point in time.
  • “Open source” is defined as: freely available technology licensed under terms compatible with Version 1.9 (or later) of the Open Source Definition, as established by the Open Source Initiative (see http://www.opensource.org/).

The Mission Statement above was ratified by the Board of Trustees on December 4th, 2014.
