Installing F#

F# comes with the .NET SDK — install the SDK and you have the F# compiler, F# Interactive, and project templates. Choose the current LTS (long-term support) release, .NET 10, from dotnet.microsoft.com/download, or use a package manager:

Windows

winget install Microsoft.DotNet.SDK.10

macOS

brew install --cask dotnet-sdk

Linux

sudo apt install dotnet-sdk-10.0      # Ubuntu
sudo dnf install dotnet-sdk-10.0      # Fedora

On other distributions, Microsoft's dotnet-install script installs the SDK into your home folder.

Check it works

$ dotnet --version
10.0.401

Your version number may be newer. Any .NET 8 or later SDK runs almost every example in this course; F# 10 features need the .NET 10 SDK.

Try it without installing

Try F# online (linked from fsharp.org) runs F# in the browser — handy for trying the smaller examples in this course.
