Script with Register-ObjectEvent hanging

I’m not sure on the action triggered . I reproduced that in 7.4 and 5. PowerShell, Return from “Wait-Event” when “Register-ObjectEvent -Action” triggers? - Stack Overflow indirectly suggests that using action with wait-event is a ‘no-no’ but unfortunately they link to another thread that’s no longer available.

No problem, it’s anyway useful, thank you!
A simple workaround is to put the same code of the Action block right after Wait-Event Timer.Elapsed:

Wait-Event Timer.Elapsed
Write-Host "Action triggered"

It works this way (even if automatic variables like $Event, $Sender, etc. will not be available).

on the second thing, I think it’s because you already waited for the event. The timer has elapsed.

Ok, so IIUC the timer expiration (that is: this specific event) can be detected by Wait-Event only once in that single PowerShell terminal. Once it has been consumed, Wait-Event is done.

Are you just playing around, or are you trying to solve an actual issue? If so, could you share the problem you are trying to solve, as there might be another way to address it?

Both the things. I am playing around and trying to better understand the Register-ObjectEvent and Wait-Event usages, because of the issues I’m having in this thread.

Thank you so much!
