Create Hello World in F#

To create a “Hello, world!” program in F#, you can use the following code:

printfn "Hello, world!"

This code will print the message “Hello, world!” to the console.

To run this code, you can save it to a file with a .fsx extension and then execute it using the dotnet fsi command. For example:

dotnet fsi hello.fsx

Alternatively, you can use an F# interactive window in an integrated development environment (IDE) such as Visual Studio or Visual Studio Code to write and run F# code.
