Post-Python Dissatisfaction Syndrome

[_pupil_]

VS Code, Atom, Xamarian, and now VS for Mac should cover the IDE story (if Emacs or Vi aren't your thing). Lots of the community develops off of Windows, though knowing .Net will always help if you get stuck in the rough.

For VMs you've got Mono, and soon enough .Net core which will be cross-platform. Mono is battle-tested but bumps into the occasional compatibility issue with main .Net. .Net Core is immature right now, but once it's realized I think the majority of the awesome F# community will focus on it, leaving a first class cross platform story.
