Question

How can I get the border in WPF to use a plain black rectangle? It always appears to have thicker bottom and left lines which I guess is a shadow effect even though I have no effects applied. I don’t want to use a rectangle as I am using this to apply a border around a grid containing controls.

Try setting SnapsToDevicePixels="true". Like this:

<Border Width="200" Height="200" 
        BorderBrush="Black" BorderThickness="1" 
        SnapsToDevicePixels="true"></Border>

For me, this removed the varying thickness of the borders.
