Great. I'm a confirmed UNIX geek and I'll be the first to say MS has always excelled at developer tools, and I'd be happy to be able to use them on Linux. (BSD is probably a pipe dream, but this is a decent start.)
If Electron (formerly atom-shell) have a BSD build/target working, it wouldn't be too hard for MS to support it... if the open-source their work on this, it'll be easier.
