<p>I'm trying to create a WPF Shape (PolyLine) editor, which is a control that I want to use to, edit shapes in a canvas.</p>

<p>What the editor needs to do is to be able to display the points and lines of the shape and to move those around.</p>

<p>Can anyone provide me with a idea of how I can accomplish this, or a starting point? I haven't found anything related to how I could do this, so far.</p>
