How to enable F# Interactive in Visual Studio Code?

Question

Issue: No F# Interactive window.

Background: I had F# Interactive working just fine then apparently did something that has made it disappear, and it's not showing when hitting Alt-Enter with code selected.

Expected Result: I thought Alt + Enter opened the FSI window with code selected but it's not happening.

EDIT: Somehow it's back. I now have F# Interactive as an option in the Terminal dropdown where as before it only had Powershell. Wierd but working...

Answer 1

Open the Command Palette with Ctrl+Shift+P and find FSI: Start command (requires Ionide extension)
