For example, when an ASP.NET 5 application is being edited in Visual Studio Code, the IntelliSense is provided by the open source projects Roslyn and OmniSharp. IMHO, the real power of this editor is its project IntelliSense for C#, TypeScript, JavaScript/node, JSON, etc.
There's a huge array of languages that Visual Studio Code supports. It also as IntelliSense for single files like HTML, CSS, LESS, SASS, and Markdown. It has more than just autocomplete (everyone has that, eh?) it has real IntelliSense. Visual Studio Code has syntax highlighting for dozens of languages, the usual suspects like CoffeeScript, Python, Ruby, Jade, Clojure, Java, C++, R, Go, makefiles, shell scripts, PowerShell, bat, xml, you get the idea. It's cross-platform, built with TypeScript and Electron, and runs on Windows, Mac, and Linux. It's a code editor, but a very smart one. Visual Studio Code (I call it VSCode, myself) is a new free developer tool. I'm down here at the BUILD Conference in San Francisco and Microsoft has just launched Visual Studio Code - a code-optimized editor for Windows, Mac, and Linux and a new member of the Visual Studio Family.
