This example shows how to set the SystemBackdrop to use Mica Alt.

<Window
    ...>
    <Window.SystemBackdrop>
        <MicaBackdrop Kind="BaseAlt"/>
    </Window.SystemBackdrop>

    <Grid RowDefinitions="*,*">
        <!-- This area has a transparent background, so the Mica
        backdrop will be mostly visible. For example, if there are
        buttons here, the backdrop will show up in the margins
        and gaps between the buttons. -->
        <Grid Background="Transparent">
            <TextBlock Text="Grid 1"/>
        </Grid>

        <!-- This area has an opaque background,
        so the Mica backdrop won't be visible. -->
        <Grid Grid.Row="1" Background="Gray">
            <TextBlock Text="Grid 2"/>
        </Grid>


</Window>

public MainWindow()
{
    this.InitializeComponent();

    SystemBackdrop = new MicaBackdrop() 
                        { Kind = MicaKind.BaseAlt };
}

Remarks

For more information about system backdrops, see Materials in Windows 11.

The backdrop is rendered behind the content specified in Window.Content. If all the content is fully opaque, this backdrop will have no visible effect.
