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
from the turorial page
or from the releases page
Download .NET 8.0 (Linux, macOS, and Windows) (microsoft.com)
2、Install
double click the exe file
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
