How to turn off the anti-aliasing in WPF shapes?

Question

I draw a rectangle using:

<Rectangle Width="300" Height="100" Stroke="Blue" StrokeThickness="6"> </Rectangle>

but there is anti-aliasing applied to it. Is there a way to turn this off? I want it to be sharp and clear.

A little late but RenderOptions.EdgeMode="Aliased" does the trick

<Rectangle Width="300"
           Height="100"
           Stroke="Blue"
           StrokeThickness="6"
           RenderOptions.EdgeMode="Aliased"/>

I have noticed significant performance degradation with this method. Perhaps it is driver bound but I have a suspicion that it falls back to software. – Gusdor Jan 23 '13 at 15:40

This doesn't actually turn off the anti-aliasing. It allows you to force WPF to render graphics to match the device or display matrix, thus prevent blurrying in some cases. The effect is similar to Mac OS X vs. Windows font smoothing. – grizzly Mar 11 '14 at 11:30

Turning off anti-aliasing is not what you are looking for, seeing as you dont have a radius applied to the corners.
