## XAML Example

```xml
<ui:LogMessage
    xmlns="http://schemas.microsoft.com/netfx/2009/xaml/activities"
    xmlns:ui="http://schemas.uipath.com/workflow/activities"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    Level="Info"
    DisplayName="Log Message">
  <ui:LogMessage.Message>
    <InArgument x:TypeArguments="x:Object">
      <VisualBasicValue x:TypeArguments="x:Object" ExpressionText="$&quot;Processing item {itemId}&quot;" />
    </InArgument>
  </ui:LogMessage.Message>
</ui:LogMessage>
```

## Notes

- `Level` is a project-level setting; the default (`Info`) can be changed project-wide in Studio project settings.
- Messages logged here are visible both in the Studio Output panel and in the Orchestrator Logs page when running attended or unattended.
- The expanded property-element form matches the common activity card and converts cleanly for C# XAML projects by replacing `VisualBasicValue` with `CSharpValue`.
