## XAML Example

```xml
<ui:TimeoutScope>
  <ui:TimeoutScope.ThrowExceptionAfter>
    <InArgument x:TypeArguments="s:TimeSpan">[TimeSpan.FromSeconds(30)]</InArgument>
  </ui:TimeoutScope.ThrowExceptionAfter>
  <ui:TimeoutScope.TimeoutMessage>
    <InArgument x:TypeArguments="x:String">Operation timed out after 30 seconds</InArgument>
  </ui:TimeoutScope.TimeoutMessage>
  <!-- child activities -->
</ui:TimeoutScope>
```

## Notes

- This is a container activity. Place the activities to be time-bounded inside its body.
- When the timeout elapses, a `System.TimeoutException` is thrown from within the scope. Use a Try/Catch around the scope to handle this gracefully.
- The `TimeoutMessage` value is surfaced as the exception `Message` property.
