Issue Details

Context: #94264

Implementation details that need validation:

  • I've named the event just Wait. MonitorWait doesn't really fit because there name Monitor is not used where the event is emitted. ContentionWait could be confused with Contention.
  • It seems like event versions start at 0 with no suffix in the name. I've started this event at 1 and added a prefix, tell me if I need to change that
  • The start event includes the same properties as ContentionStart: ClrInstanceID, LockID, AssociatedObjectId but no ContentionFlags or LockOwnerThreadID
  • It could be interesting to add a ThreadID property. It would also help to have a IsThreadPoolThread but I don't think there is a concept of thread pool at that level
  • The new event is under the keyword contention (0x400). I think it makes sense to collect it whenever the contention events are collected
  • No changes are required on the Lock class because it doesn't support the wait operation

It doesn't compile, the FireEtwWaitHandleWaitStart function is not generated. I'll continue tomorrow.

The console log for the failure is almost empty, not sure what might have happened. Previous failures of the test didn't look similar. It seems to have passed on rerun.
