Use F# on Linux

Option 1: Install the CLI tools and use your own editor

Install the .NET SDK. .NET is available for major Linux distributions and is typically installed with the system package manager of your distribution of choice.

Once that is installed, you can begin using F#!

Create a file called hello.fsx that looks like this:

printfn "Hello World from F#"

Now compile and run this F# script with the following command:

dotnet fsi hello.fsx

If this is your first time using .NET, there will be a short, one-time message about using the .NET SDK. After that, you’ll see the following output in your console:

Hello World from F#

To create a project use

dotnet new console --language F#
dotnet run

You will see a message saying “Hello World from F#”.

For more information see Getting started with the F# command line tools.

Option 2: Install Visual Studio Code and Ionide

Visual Studio Code is a free, open source, cross platform source code editor supporting a lot of languages. F# is supported by the Ionide project.

1. Install the .NET SDK like in step 1.

2. Install Visual Studio Code.

3. Press Ctrl+Shift+P and enter the following to install the Ionide package for VS Code.

    ext install Ionide-fsharp
   

You can also install the plugin from the plugin pane on the left-hand side.

Ionide works best if you use the .NET CLI to create your projects. You can learn more in Get Started with F# in Visual Studio Code.

Option 3: Install JetBrains Rider

JetBrains Rider is a cross-platform .NET IDE built using IntelliJ and ReSharper technology. It offers support for .NET applications on all platforms.

You can install JetBrains Rider from here.

Option 4: Build F# from source

You can build and contribute to the F# compiler and library from the source.
