ThreadException notice confusing

https://docs.microsoft.com/en-gb/dotnet/api/system.windows.forms.application.threadexception?view=netframework-4.7

On the `Application.ThreadException` page - there is the below notice:

> Caution
> Because this is a static event, you must detach your event handlers when your application is disposed, or memory leaks will result.

That confused me - surely the event will be disposed when the application ends anyway? Or is this suggesting that some resources may be kept hold of, once my application has already terminated?

I looked at the code example on that page, which seems to do no special handling regarding this notice. I then Googled it - and seems I wasn't the only person confused:

Is the explanation on StackOverflow correct? If so - that seems a niche case to pull out in a big red **Caution** box - could the situation be clarified?

Inizia dalla pagina dell'API Application.ThreadException ed esamina l'avviso di cautela e il relativo esempio di codice. Confronta l'avviso con le discussioni collegate di Stack Overflow e PCReview; il lavoro è completato quando la documentazione spiega accuratamente quando è necessario scollegare gli handler e se l'avviso richiede chiarimenti.
