Fondo negro de ventana de WPF

Question

Creé una ventana simple y le apliqué estilo. Ahora, cuando corro aplicación de fondo es negro:

En XAML se ve normal:

qué está causando esto?

Aquí es el código XAML:

<Grid Name="LayoutRoot" HorizontalAlignment="Stretch" VerticalAlignment="Stretch" Background="White"> 
         <Grid.RowDefinitions> 
          <RowDefinition Height="*" /> 
          <RowDefinition Height="Auto" /> 
         </Grid.RowDefinitions> 
         <Grid Grid.Row="0"> 
          <ContentPresenter /> 
         </Grid> 
         <StatusBar Name="statusBar1" Height="23" HorizontalAlignment="Stretch" VerticalAlignment="Top" Grid.Row="1" /> 
         </Grid> 

Debido a que está sustituyendo la plantilla por defecto de la ventana se le está quitando los efectos de estilo (de los cuales uno es de fondo = negro en la parrilla de la raíz)

ver más arriba, lo he puesto en la plantilla y ahora debería funcionar (fondo = "White")

a continuación se muestra la plantilla por defecto para una ventana (tomado de Mezcla)

<ControlTemplate x:Key="WindowTemplateKey" TargetType="{x:Type Window}">
