I found the solution at: http://msdn.microsoft.com/en-us/library/system.windows.media.renderoptions.setedgemode.aspx

<Image Stretch="None" RenderOptions.EdgeMode="Aliased">
RenderOptions.SetEdgeMode(this, EdgeMode.Aliased);

Answer 2

I saw a similar issue with the Border control, although @phi your solution worked in most cases I also had to add the following to get it to completely work:

SnapsToDevicePixels="True"

Answer 3

Change the middle line to:

<LineGeometry StartPoint="0,6" EndPoint="50,6"/>

You can get a crisp line on a pixel boundary by placing the line on a whole numbered unit.
