The F# Language, Library, and Visual F# Tools Repository
You are invited to help produce future releases of the F# language compiler, library, and tools. This repository enables development on Linux, macOS and Windows, along with some automated CI testing for these.
The F# Compiler and Tools are also mirrored in the corresponding repository of the F# Software Foundation.
Changes contributed here are eventually propagated to this repository and are included in all packagings of F# and open source F# editing tools. The process for doing this is explained in this guide by the F# Core Engineering Group. Currently, the F# community coordinates packaging other editions of F# for use on Linux, macOS, Android, iOS, and other platforms, and Microsoft coordinates packaging this repository as part of the Visual F# Tools.
For historical reasons this repository is called "visualfsharp" and currently also contains the Visual F# IDE Tools. The eventual plan is to split these repositories into "fsharp" and "visualfsharp".
Help improve the Quality of the Tools by Using the Nightly Releases of Visual F# Tools
To setup Visual Studio to use the latest nightly releases of the Visual F# Tools: https://blogs.msdn.microsoft.com/dotnet/2017/03/14/announcing-nightly-releases-for-the-visual-f-tools/
To contribute to the F# ecosystem more generally see the F# Software Foundation's Community Projects pages.
These are the branches in use:
master= Latest branch for OSS developers and nightly users.
- Most contributions go here.
- Able to be built, installed and used in the latest public Visual Studio release.
- May contain updated F# features and logic.
- Used to build nightly VSIX (see above).
- Gets integrated into https://github.com/fsharp/fsharp to form the basis of Mono releases
- Gets integrated into https://github.com/fsharp/FSharp.Compiler.Service to form the basis of FSharp.Compiler.Service releases
- Latest release branch for the particular point release of Visual Studio.
- Incorporates features and fixes from master up to a particular branch point, then selective cherry-picks.
- May contain new features that depend on new things or fixes in the corresponding Visual Studio release.
- Gets integrated back into master once the corresponding Visual Studio release is made.
- Used to build Visual F# Tool updates

Using Nightly Releases of Visual F# Tools
To setup Visual Studio to use the latest nightly releases of the Visual F# Tools:
Using CI Builds
To install F#, see http://fsharp.org.
To download the bits for the latest CI builds see these instructions. This includes and ZIPs containing the F# compiler and VSIX installers for the Visual F# IDE Tools.
Using F# on a build server or computer without an F# installation
If you wish to use the latest F# compiler on a computer without Visual Studio 2017 installed, you can add the nuget package
FSharp.Compiler.Tools to your projects. This will replace the in-box compiler with the version contained in the package.
The actual package is built in https://github.com/fsharp/fsharp.
You will need to adjust the targets reference on your project file to use the targets file from the installed
See https://github.com/fsharp/fsharp/issues/676 for how to modify your project file.
