Their integration for TypeScript and GoLang are first class as well. Overall though I held the same excitement for Atom as you did (and I used to use Emacs for everything because I wanted an open editor in my tool belt) I've really come to appreciate the approach and polish of VSCode.
I don't see how it would make a difference though, running "nuget restore" only takes a second or two.
An editor that is not "hacked" together on idiotic technologies ("web" "dev"), but a well designed editor, written for performance, on top of the best technology for that specific job.
emacs pretty much runs everywhere
And there is a webkit extension to turn emacs into a browser. I wonder how well atom will run in emacs
That's why emacs has existed for decades now.
Large files, slowish startup, and the like are all special case problems that I can use Sublime for, but until now, the almost subliminal typing sluggishness always drove me away.
Bravo Atom team for making it fast enough. I look forward to continued improvements in this space.
