This issue has been moved from a ticket on Developer Community.

[severity:It bothers me. A fix would be nice] [regression] [worked-in:17.2] While building my project, I opened a file that was created via the new "source generators" feature and encountered a gold bar with this error: Feature 'Missing import discovery' is currently unavailable due to an internal error.

Please see attached trace files and screenshot.

This feature assumes the document is not a source generated document, and provides no handling for the case where the document does not exist:

Thanks for taking a look at this, @sharwell 🙂 BTW, were the traces from VS helpful in this case?

VS Load Errors

After the last VS upgrade I am constantly getting these errors. (See image)

If it helps - copilot and all other AI is blocked on our networks. I started noticing the slow failure of VS as Copilot became available.
