/// note | Detalles Técnicos

Si tienes dependencias con `yield`, el código de salida se ejecutará *después* del middleware.

Si hubiera tareas en segundo plano (cubiertas en la sección [Tareas en segundo plano](background-tasks.md){.internal-link target=_blank}, lo verás más adelante), se ejecutarán *después* de todo el middleware.
