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".

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 FSharp.Compiler.Tools package. See https://github.com/fsharp/fsharp/issues/676 for how to modify your project file.
