I'm not sure if you saw, but you can keep it and do the same things as well in the future. "Microsoft says the language services it built for Visual Studio Code will be available in other editors as well, including Sublime Text, Vi and Atom."
As an example, the OmniSharp engine that powers C# completion is available for Emacs, Vim, Sublime, Atom, Brackets, etc. http://www.omnisharp.net/
I still love Sublime and will use that for all other non-.NET/C# purposes.
