Ionide, The F# language server, is excellent.

I use F# in .NET Interactive Jupyter notebooks daily at work and it works quite well.

The community around the language is very helpful and the Discord is great for all sorts of issues ranging from beginner to advanced.

I love the Fable compiler which targets JS, TS, Python and Rust and makes for a wonderful way to share a domain design across multiple code bases.

I haven't really used the Ionide plugin for VSCode, but I did make pretty liberal use of the Emacs plugin (well, Spacemacs), and it was pretty solid. I used it almost exclusively for about a year; I don't know if the Emacs plugin uses Ionide behind the scenes, but I thought it was pretty decent overall.

Still, once Rider got a few updates and was stable, it was kind of hard to go back. I'm a pretty dedicated Vim dude normally, but for a lot of "enterprisey" things like .NET and Java the ability to do smart refactoring of lots of files and integrated debuggers really do become a pretty substantial value-add for me.
