    <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"></Grid>

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

public MainWindow()
{
    this.InitializeComponent();
