/// tip

You can use `async` or regular functions.

**FastAPI** will do the right thing with each, the same as with normal dependencies.

///

## A dependency with `yield` and `try`

If you use a `try` block in a dependency with `yield`, you'll receive any exception that was thrown when using the dependency.

Auf diese Weise weiß die Unteranwendung, dass sie dieses Pfadpräfix für die Benutzeroberfläche der Dokumentation verwenden soll.

Und die Unteranwendung könnte auch ihre eigenen gemounteten Unteranwendungen haben und alles würde korrekt funktionieren, da FastAPI sich um alle diese `root_path`s automatisch kümmert.
