The following example demonstrates the use of this property:

<Style x:Key="{x:Type ToolTip}" TargetType="ToolTip">
  <Setter Property="OverridesDefaultStyle" Value="true"/>
  <Setter Property="HasDropShadow" Value="True"/>
  <Setter Property="Template">
    <Setter.Value>
      <ControlTemplate TargetType="ToolTip">
        <Border Name="Border"
          Background="{StaticResource LightBrush}"
          BorderBrush="{StaticResource SolidBorderBrush}"
          BorderThickness="1"
          Width="{TemplateBinding Width}"
          Height="{TemplateBinding Height}">
          <ContentPresenter
            Margin="4" 
            HorizontalAlignment="Left"
            VerticalAlignment="Top" />
        </Border>
        <ControlTemplate.Triggers>
          <Trigger Property="HasDropShadow" Value="true">
            <Setter TargetName="Border" Property="CornerRadius" Value="4"/>
            <Setter TargetName="Border" Property="SnapsToDevicePixels" Value="true"/>
          </Trigger>
        </ControlTemplate.Triggers>
      </ControlTemplate>
    </Setter.Value>
  </Setter>
</Style>

The above example uses the following resources:

<LinearGradientBrush x:Key="LightBrush" StartPoint="0,0" EndPoint="0,1">
  <GradientBrush.GradientStops>
    <GradientStopCollection>
      <GradientStop Color="#FFF" Offset="0.0"/>
      <GradientStop Color="#EEE" Offset="1.0"/>
    </GradientStopCollection>
  </GradientBrush.GradientStops>
</LinearGradientBrush>

  ...

<SolidColorBrush x:Key="SolidBorderBrush" Color="#888" />
