Remarks

This event is raised when an exception that was thrown during execution of a delegate by way of Invoke(Action) or InvokeAsync(Action) is uncaught. A handler can mark the exception as handled, which will prevent the internal exception handler from being called. Event handlers for this event must be written with care to avoid creating secondary exceptions and to catch any that occur. It is recommended to avoid allocating memory or doing any resource intensive operations in the handler.
