Visual Studio Code has a very modular architecture. The tool itself is written in Node.JS and web technologies, on top of Electron, and most extensions have a Javascript component. But most of the language and debugging functionality is built as out-of-process components, which means that they can be built in any technology. For example, our Typescript and Node tools are built with Node; our .NET tools are built in .NET and native code; and most of the functionality of our Go extension is built (by the Go community) in Go.

PTVS is written in a combination of .NET and Python - but with CoreCLR available across all platforms, a lot of that code can be reused. The way they integrate into the tools may be different, but they can share a lot of common code.

Interesting. I have been looking for a good editor, I use Sublime now, but I want somethign a bit more modern.

This is worrying. I think Atom is a really cool editor, and it seems to have come a long way, has a lot of great features and an awesome UI. However, it is buggy and slow as hell. It crashes and behaves unexpectedly, causing it to crash and either lose changes, or need to be restarted.

I try it once every few months, most recently this week. Does VS Code behave the same way? I copied a 1000 line JSON object into Atom yesterday, and it basically crashed, how do you find VS performance?

Ya, Electron != Atom. Grab Code and paste that giant JSON into Code and let us know how it goes.

visual studio code seems way faster, pasting the object was nearly instantaneous and it looks like it has a nice set of features. also, i feel i should add, i realize electron is independent of atom, however it was developed by a github engineer previously working on nodewebkit for the github texteditor called atom. it used to be called "Atom Shell" and is in the atom/electron repo. So I was curious if this was related to electron generally, or choices made in atom.

Electron was indeed originally called Atom Shell, and part of Atom. But it's a general purpose shell for cross-platform apps - it basically provides a native application shell hosting Chromium. And lots of apps - including many that aren't developer tools - are built on it. While VS Code uses Electron, and we contribute to it, we've made a lot of design choices differently from Atom in building the editor and rest of the product.

Code is definitely not Atom. You should give it a try. It's free.
