As announced by the Visual F# team today at StrangeLoop 2012, the open source code drop for F# 3.0 is now available!

This code drop comes right on the heels of the release of F# 3.0 as part of Visual Studio 2012, and the Free Tools for F# for use with Visual Studio 2012 Express for Web. We have also recently released some great new samples showing the uniquely powerful features of F# 3.0.


The F# 3.0 open source code drop augments the commitment Microsoft make to F# through Visual F# in Visual Studio 2012. From an engineering perspective, one major reason we’re doing this code drop is tool development - a source drop enables the F# community to develop and contribute a range of tools for F#. These can be UI tools such as code visualizers, or editing tools such as refactorings, or new ways of executing, hosting or interpreting F# code, or indeed whole new F# editing experiences.   The F# community use the code drops to help make F# available for a broader range of environments including Mono, MonoDevelop, Mac and Linux.


The source code is under the Apache 2.0 license and is published as part of the F# PowerPack codeplex project, which is also under the Apache 2.0 license.


If you want to use F# 3.0 today on Windows, you should use one of the installations of Visual Studio 2012 available at the F# MSDN Developer Center. 


If you would like to join the F# Open Source Community and help bring F# to a wider range of platforms, you can join the discussion group. The community do most development on GitHub - they take the drops of the F# compiler from the Visual F# team from CodePlex and incorporate them into the GitHub repository. 

The Visual F# team use a “code drop” model, where we make available versions of the compiler+library code logically matching each release of the F# language itself. In the F# team, releases of F# have so far been matched to coincide with releases of Visual Studio itself: using this release cadence simplifies our development processes and gives clarity to language versioning. This means the code we are making available today is for the F# 3.0 language, released in August 2012.


As this release is a code drop, it does not contain binaries for the release. This means you still get F# from, so the place to “get” F# doesn’t change with this release.

  • To get or learn F# 3.0, or learn why F# is important, go to
  • To use F# 3.0 in Visual Studio 2008 or Visual Studio 2010, including with the free tools, go to
  • To get the compiler+library source code drop, go to the F# PowerPack and look for directory compiler\3.0

    Ummm, previously I've managed to figure out where to get F# for Linux binaries, but I don't see anything labelled "F# 3.0 for Linux" at that URL - just Visual Studio stuff?

  • Amazing.

    Thanks for the great work guys!

  • Anyone for a direct link on how to use F#3.0 in VS2010 ?

  • Thank you F# Team

    Great work !

    I can now update F# Refactor to use F# 3 :-)

  • @Isaac : The code is here: You may need to bootstrap with an F# 2.0 compiler.

  • @ildjarn: it was clear where the source code was, and it was clear that there were no binaries.

    As a practical matter, my mono install was not in one of the standard locations, and I gave up trying to compile F# 3.0 using that custom install.

    I re-built and re-installed mono, and then dropped fsharp-fsharp-1e30952 into the mono-3.0.0 source directory. After that re-organisation the F# 3.0 compiler built just fine.

  • Maybe I'm missing something, but how do I get F# 3.0 if I have visual studio 2010? just redirects to a msdn site with no downloads for anything other than visual studio 2012
