Avalonia user control with design time XAML property setter

Avalonia user control with design time XAML property setter

In Avalonia, you can set design-time XAML property values for user controls to improve the visual designer experience. This is achieved by using the `d:` (Design) prefix, similar to WPF. For instance, to display a sample `Header` text in the designer for a `MyCustomControl`, you would write `--local:MyCustomControl d:Header="Sample Header" /--`. The `d:` prefix indicates that these properties are purely for design-time use and are ignored during runtime, allowing you to visualize your control's layout and appearance with specific data or states without needing to instantiate the actual control with live data at design time. This enhances productivity by providing immediate visual feedback.
