Visual studio is anything but legacy and I haven't found anything better. Where does the future lie?
Almost always when somebody shits on Visual Studio s/he either uses C++
(and there's significant difference apparently between C++ and C#) or used it with Resharper, or without any extension/addon at all.
Just try Roslynator if you haven't used it yet.
Especially when it comes to web. Visual Studio still dies of stroke as soon as someone dares whisper the word "razor" in its vicinity, while Rider has no problem understanding Razor templates and providing full autocompletion.
Not to mention Rider is just straight out snappier. And has integrated terminal without any need for extensions.
