For instance, in the event of an unhandled exception in a manually created thread, the application will crash (unless handled via AppDomain.CurrentDomain.UnhandledException), but with.LongRunning, it will be wrapped into a Task as an AggregateException. It's always faster to directly return the Task since it does less work but you end up changing the behavior and potentially losing some of the benefits of the async state machine. ⚠️ It might be tempting to update the logic in DisposableThing.Current to mutate the original execution context instead of setting the async local directly ( StrongBox<T> is a reference type that stores the underlying T in a mutable field):
