@JL03-Yue it'd be good to investigate by Feb in case there's a 9.0 regression.

@marcpopMSFT it also repros on newer builds of 8.0.200-preview. Should this be looked at sooner then though 8.0.200-preview is not going to be released standalone?

Potentially a regression from #36505?

[marcpopMSFT]

Ahh, I didn't notice it was reported in 2xx as well. @JL03-Yue , do you think you'll have time to investigate by Jan 5th for a 2xx fix? That's when VS starts locking down.

[JL03-Yue]

This is caused by the recent merge of #36505. I wonder either we should document it somewhere or revoke the merge

[baronfel]

There should be a documented change, yes - we also need to fix the fact that the Skipping NuGet package signature verification message was emitted in quiet mode.
