I use WSL full time and VSCode (installed on Windows).
However, I also run my web apps in Docker so I don’t have to worry about installing things directly inside of WSL’s filesystem. At some point in the future VSCode is going to support seamlessly finding interpreter and library code running in a container instead of the local machine, so if you happen to use Docker, you’ll get the best of both worlds.
For the time being, I don’t even use extensions like Elixir-LS. I just installed vscode-elixir to get syntax highlighting.
Overall I’m super happy with the set up. I never liked heavy auto-complete because I find it creates micro-stutters and 95% of the time it gets in the way. My philosophy has always been to use snippets (works just fine with WSL) to help deal with code complete / boilerplate.
