PTVS team lead here. it's coming, promise :) we're working on untangling all the VS-ness out of PTVS so it can run in the VSC environment. overall team is small & we've been busy doing RTVS, and Jupyter notebooks. hopefully later this calendar year.

There's still half a year left from that promise.

There was an issue raised 2 months ago: https://github.com/Microsoft/vscode/issues/4625 which says they're going to begin work in a not too distant future. You can always bring it back up if you need a more updated answer.

If you read down a little bit you'll see this...

"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."

So, it doesn't look like it's going to happen until CoreCLR is stable.

It's alright with the Python extension. It has Intellisense, code folding, and the like.

I've used VSCode but I still prefer vim for JS.
