Visual Studio Code + Ionide extension is much lighter weight than visual studio proper. FSX (fsharp script files) can then be written and executed directly and will cover this gap. Technically you don't need the former, you can pipe the FSX file directly into the fsharp interactive EXE that interprets them from notepad and console if you like.
