VS Code -- Are there user/support forums or an IRC channel?
Here's a rough guide of which communications channel to use:
For issues / feature requests, please file a GitHub issue: https://github.com/Microsoft/vscode/issues/new
For general "how to" questions, StackOverflow is probably your best bet
For other discussions, try https://gitter.im/Microsoft/vscode or Twitter
The IRC channel on Freenode is ##vs-code.
there appear to be 3 separate VSCode support channels on freenode, i ordered them by apparent population:
irc://irc.freenode.net/#VSCode (24 people connected as of writing)
irc://irc.freenode.net/##vs-code (22 people connected as of writing)
irc://irc.freenode.net/##VSCode (10 people connected as of writing)
as of writing means: 2019-05-26T12:40:21+00:00 (ISO 8601)
