Setting environments
- Option 1: Try it in your browser
Try F# (fsharp.org) is based on Fable 2.0.11
Fable REPL is based on the latest version
Let's try the lastest version, open https://fable.io/repl/
input or copy and paste code below in the edit area, press the run button on the left sidebar
let hello = "Hello, World!"
printfn $"{hello}"
you will see the output of your code on the Console window at lower right corner, good start!
- Option 2: Install .NET8 SDK
.NET8 SDK includes everything to compile and run F#
Install on Windows for example:
1、Download .Net 8 SDK
or from the releases page
Download .NET 8.0 (Linux, macOS, and Windows) (microsoft.com)
2、Install
click install, follow the hints, click next until it finished
open a new command window
3、Test installation
copy/input the following command on the command window you open just now, to test if your environment is ready
dotnet --version
output
Official guide how to set environment on you computer:
F# Tutorial | Hello World in 5 minutes | .NET (microsoft.com)
you can follow the official guide if you're using Linux or macOS, all our code in the following articles will be running on Windows(10/11)
it should not be a problem if you're not using Windows, as F# is expected to run on Linux or macOS without change, it's not guaranteed 100% though
