title: How to draw an arrow in WPF programatically?
body: <p>I need to draw an arrow in WPF programatically. I remember that Windows Forms had primitives to draw an arrow, setting the <code>Cap</code> to the <code>Pen</code>.</p>
  
  <pre><code>mMyPen.CustomEndCap =
      new AdjustableArrowCap(arrowSize, arrowSize, true);
  </code></pre>
  
  <p>Is it possible with WPF?</p>
