The point I made in the post is that while VS might be better with C#, Emacs works well with everything, works Good Enough with most languages, and pretty good for C#. In fact, looking over the feature list for Emacs C# editing (https://www.emacswiki.org/emacs/CSharpMode), I can't find anything obviously missing from VS.
In any case, I don't want to learn a new environment every time I change languages.
