WPF drop shadow

Question

Currently I'm making something in WPF that has a border that contains a grid and other controls. The problem I'm facing is that whenever I set the Border.Effect property to a drop shadow effect every control contained in the border now has a drop shadow. Is there a way to set the shadow just to the border and not every control contained in the border?

Here is a short example of my code:

<Grid>
 <Border Margin="68,67,60,67" BorderBrush="Black" BorderThickness="1" CornerRadius="10">
  <Border.Effect>
   <DropShadowEffect/>
  </Border.Effect>
  <Rectangle Fill="White" Stroke="Black" Margin="37,89,118,98" />
 </Border>
</Grid>

Two choices either add a border element with the effect on it as a sibling of the border / rectangle element tree you have. Something like this:

<Grid>
    <Border Margin="68,67,60,67"
            BorderBrush="Black"
            BorderThickness="1"
            CornerRadius="10">
        <Border.Effect>
            <DropShadowEffect />
        </Border.Effect>
    </Border>
    <Border Margin="68,67,60,67"
            BorderBrush="Black"
            BorderThickness="1"
            CornerRadius="10">

        <Rectangle Fill="White"
                   Stroke="Black"
                   Margin="37,89,118,98">
        </Rectangle>
    </Border>

</Grid>

Or put the rectangle as a sibling of the border element like this:

   <Grid>
    <Border Margin="68,67,60,67"
            BorderBrush="Black"
            BorderThickness="1"
            CornerRadius="10">
        <Border.Effect>
            <DropShadowEffect />
        </Border.Effect>
    </Border>
    <Rectangle Fill="White"
               Stroke="Black"
               Margin="37,89,118,98">
    </Rectangle>

</Grid>

NOTE: You will have to tweak the layout on the second solution to make the rectangle line up where you want it
