> One is lagging support in Visual Studio
I use VS Code, both for Python and now for F#, and so far my experience has been positive. But that might be because I've used F# only for very basic stuff, and I don't know how better it could be in some other language and/or IDE.

I think I'll stick with Python for that :) But I'm thinking about maybe transferring some machine learning stuff from Python to F# in (some distant) future.
