The Microsoft Visual F# team are pleased to announce the availability of our code drop of an F# 3.1 compiler, library and tests.

This code drop corresponds to the release of the Visual F# Tools for F# 3.1 as part of Visual Studio 2013. We have also recently released some great new samples showing the unique power of F#.

F# is an open, cross-platform language and you can read testimonials about how F# is used in the software industry at the pages of the F# Software Foundation, a major community organization for the F# language.

The Visual F# Tools team at Microsoft contribute to F# through enterprise-ready tooling in Visual Studio 2013. We recommend the Visual F# Tools as the best, most productive and highly stable route for functional-first programming in the Windows ecosystem.   You can find out more about functional-first programming in industry in the recent talk Succeeding With Functional First Programming in Industry at NDC Oslo, and at the excellent website F# for Fun and Profit (external link). You can also learn F# in your browser using Try F#.

Functional-first programming is a general-purpose programming technique represented by langauges such as Clojure, Scala, Haskell, F#, OCaml and is particularly suited to analytical programming tasks such as calculation engines, data-science programming, ETL pipelines and general data-manipulation. While these problems can be solved using other programming paradigms, they are particularly amenable to functional-first programming. Functional-first programming uses functional programming as the initial paradigm for most purposes, but employs other techniques such as object-oriented programming and state manipulation as necessary.   

If your organization decides to invest in functional-first programming, then we recommend you use the Visual F# Tools from Microsoft.

The F# community contribute a range of tools for use with F#. Some incorporate F# language tooling and can be UI tools such as code visualizers, editing tools, or new ways of executing, hosting or interpreting F# code, or indeed whole new F# editing experiences.   For example, the following F#-related tools are made by the F# community (some are commercial, some are open):

These and others make F# programming available for a broad range of situations, including many not covered by the Visual F# Tools from Microsoft.

Other libraries and tools contributed to F# include:


If you want to use F# 3.1 today on Windows, you should use one of the installations of Visual Studio 2013 available at the F# MSDN Developer Center. For free Visual F# tools for Windows you should currently continue to use F# 3.0 in the Visual Studio 2012 F# web tools (we are actively pursuing an F# 3.1 update for this). 

If you would like to join the F# Community and help improve F# tooling and across multiple platforms, you can join the discussion group. The F# community do most development on GitHub - they take the code drops of the Visual F# Tools team from CodePlex and incorporate them into the GitHub repository.

This source code drop is under the Apache 2.0 license and a reference copy is published on CodePlex. It has already been integrated into the fsharp_31 branch of the primary repository of the F# community on GitHub.

As this release is a code drop, it does not contain binaries for the release.

  • Please add 4 and 4 and type the answer here:
  • Post
  • why 3.1 is not master and why master is not 3.0 on github?

  • I'd venture to say that tooling for any language can't be considered "enterprise-ready" until it supports refactoring. Any progress on that front? Granted that TypeScript is a simpler language, it's quite telling that TS had refactoring support in its very first public alphas, and I think that support has a great deal to do with the acceptance it's received so far.

  • Thanks for the good work with F# language going forward and making ML derived languages first class on Microsoft world.

    When can we see some more Visual Studio tooling love (refactoring, WPF, VS Express, WP 8.x, ...) for F# developers?
