The Combined F# Language, Library, and Tools Repository
You are invited to help producing future releases of the F# language compiler, library, and tools.
F# is a mature, open source, cross-platform, functional-first programming language which empowers users and organizations to tackle complex computing problems with simple, maintainable, and robust code. F# is used in a wide range of application areas and is supported by industry-leading companies providing professional tools, and by an active open community. You can find out more about F# at http://fsharp.org.

Code Flow to Packagings of F#
This repository enables development on Linux, macOS and Windows. It enables automated CI testing for some of these.
Changes contributed here are eventually included in all packagings of F# and open source F# editing tools. Microsoft coordinates packaging this repository as part of the Visual F# Tools, and the F# community coordinates packaging other editions of F# for use on Linux, macOS, Android, iOS, and other platforms.
Using
For typical installs of F#, see http://fsharp.org.
Using Nightly Releases of Visual F# Tools
To setup Visual Studio to use the latest nightly releases of the Visual F# Tools, follow the Using CI Builds instructions.
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 fsharp/fsharp#676 for how to modify your project file.
