VS Code is still in preview and, at the time of this writing, lacks support for debugging ASP.NET 5 apps (although it’s promised soon). So why would you want to forsake full-blown Visual Studio running on Windows for a stripped down version running on OS X?
To get started setting up and using VS Code, check out the docs. For that you’re going to need either a souped up text editor (such as Sublime Text, Brackets, Atom, Emacs or Vim) together with OmniSharp for intellisense, or you’ll want to use Visual Studio Code, the new cross-platform IDE from Microsoft that uses OmniSharp with Roslyn and provides Git integration for version control, plus limited debugging support. The day has arrived when you can both develop and deploy an ASP.NET application on an Apple Mac.
