@steveharter It looks like Reflection might be in the call stack here and a couple folks from this area pod are away from work right now. Can you take a look please?

It looks like Reflection might be in the call stack here

Reflection is only in the call stack because XUnit uses reflection to invoke the test methods.

Likely related to #73739 since they use the same test helpers and the failure occurred around the same date.

The failure indicates the actual target test method LengthyAction_ThrowFromFinally was not called, since the first line of code in that method sets _startedExecution = true and the assert that is failing checks against that.

Stack is:

RunTest(LengthyAction_ThrowFromFinally, cts.Token);
->ControlledExecution.Run(action, cancellationToken);

And since ControlledExectution is new, that should be investigated -- AntonLapounov PTAL.
