@davidfowl I'm concerned this happened on the first official build with your changes to WebApplicationFactory #33462.

Oh snap! Very nice

[davidfowl]

OK so psychic debugging tells me a couple of things:

• OSX only? Weird
• I would expect this to happen everytime if it was a problem not sometimes. It looks like it keeps failing on OSX.
• StartAsync triggered the IHostApplicationLifetime since StartAsync completed.
• WaitForShutdownAsync might be throwing and causing it to finish early, causing it to be disposed.

[davidfowl]

I know why this happens. These tests run in parallel and this event is global. I'll need some time to re-think this a little 😄

[davidfowl]

OK dotnet/runtime#54090 should resolve this.

[davidfowl]

Waiting until that change propagates

[davidfowl]

Should be fixed by #33479
