Thank you, that was a really helpful comment! That seems to have been the problem. I had Visual Studio installed already and I just reran an installer and that gave me the option to install F#. That I needed to run the installer for visual studio again, that I couldn't just install F# support some other way, that just wasn't clear to me. I have to say that messing around in visual studio in F# just now was extremely painful. I had to press shift+enter to add a new line, just enter did nothing. Tab didn't indent. I don't know what indents. I don't know what key does the job backspace is supposed to do (delete the previous character). I don't really understand why everything is so hard. I don't have this problem with Visual Studio C++ files. O_o To be honest I'd prefer using VS Code to write F# and build from the command line, do you know of any good getting started guides? I'll check the VS Code extension documents, maybe now that I have it working in VS Code this will be easier. Thank you for your help so far!
