I’ve been curious about neovim too, I’m planning on biting off too much with this little walkthrough:

Hi, thank you for responding, sorry for my incomplete reply.

After running dotnet fsi on the command line, I tried in vs code again. FSI Start…and it worked!

So I don’t know if it need a “first run” or something changed between last night and now…but oh well. Thank you for your help!

dotnet fsi

that works, was there a breaking change or is my vscode setup borked?

It says it’s not in the path, and indeed…poking around the sdk 7 folder I don’t see FSI.exe, I see FSI.dll but of course you can’t run a dll by name alone.
