You can install F# in multiple ways, depending on your environment.
Install F# with Visual Studio
If you're downloading Visual Studio for the first time, it will first install Visual Studio Installer. Install the appropriate edition of Visual Studio from the installer.
If you already have Visual Studio installed, choose Modify next to the edition you want to add F# to.
On the Workloads page, select the ASP.NET and web development workload, which includes F# and .NET Core support for ASP.NET Core projects.
Choose Modify in the lower right-hand corner to install everything you've selected.
You can then open Visual Studio with F# by choosing Launch in Visual Studio Installer.
Install F# with Visual Studio Code
Ensure you have git installed and available on your PATH. You can verify that it's installed correctly by entering
git --versionat a command prompt and pressing Enter.
Select the Extensions icon and search for "Ionide":
The only plugin required for F# support in Visual Studio Code is Ionide-fsharp. However, you can also install Ionide-FAKE to get FAKE support and Ionide-Paket to get Paket support. FAKE and Paket are additional F# community tools for building projects and managing dependencies, respectively.
Install F# with Visual Studio for Mac
F# is installed by default in Visual Studio for Mac, no matter which configuration you choose.
After the install completes, choose Start Visual Studio. You can also open Visual Studio through Finder on macOS.
Install F# on a build server
If you're using .NET Core or .NET Framework via the .NET SDK, you simply need to install the .NET SDK on your build server. It has everything you need.
If you're using .NET Framework and you are not using the .NET SDK, then you'll need to install the Visual Studio Build Tools SKU onto your Windows Server. In the installer, select .NET desktop build tools, and then select the F# compiler component on the right-hand side of the installer menu.
