Se você tiver dependências com `yield`, o código de saída será executado *depois* do middleware.

Se houver alguma tarefa em segundo plano (abordada na seção [Tarefas em segundo plano](background-tasks.md){.internal-link target=_blank}, que você verá mais adiante), ela será executada *depois* de todo o middleware.
