interactive: Missing syntax highlighting in Polyglot Notebook extension when launched from dev container

I have the same problem with polyglot notebooks running locally. I can get syntax highlighting to work by clicking the “Select Cell language mode” button which defaults to “Code”. I can then click auto detect, and syntax highlighting works again, however the cell will no longer run.

What do you mean by autodetect?

@colombod In vscode, when you click Select Cell Language mode on a code cell, it brings up the command pallet, where if you click Auto Detect, it changes to whatever language you are using.

Same here on WSL. In recent versions(since the very beginning of Jan 23, when I had this issue), syntax highlighting seem to be fine before .NET Interactive extension activation (tested by creating a new polyglot notebook with .ipynb, put some code in and reload window to see the colors disappear after this extension loaded). If I downgrade the extension to 1.0.3553070(labeled as 3 months ago), basic language features like syntax highlighting works but suggestions still doesn’t have any styling. About the extensions that I currently enabled, almost all of them are remote development support published by Microsoft.

@shiftybit it fixes the color only, and I if I open and close it, it dissapers. When I try to execute with anything but code there it doesn’t execute it.

Same here. But onlye when working on a dev container. When working local on Windows 10, it works fine.
