Use F# on macOS
Option 1: Install the CLI tools and use your own editor
Install the .NET SDK.
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 Core, 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
Install .NET Core SDK like in step 1.
Install Visual Studio Code for macOS.
Cmd+Shift+Pand 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 Visual Studio for Mac
Visual Studio for Mac is a free IDE for general purpose development. It supports a wide range of projects that you can use F# with.
You can learn more at Get started with F# in Visual Studio for Mac.
Option 4: Install JetBrains Rider
JetBrains Rider is a cross-platform .NET IDE built using IntelliJ and ReSharper technology. It offers support for .NET and .NET Core applications on all platforms.
You can install JetBrains Rider from here.
Option 5: Build F# from source
You can build and contribute to the F# compiler and library from the source.
