title: How can I draw a circle sector with the ellipse class?
body: <p>I would like to make a sector of a circle on WP7. I tried to do this with the ellipse class and I found a lot of solution, which make a gauge or pie chart or something, but I need just the essence.
  Could anyone help?</p>
  
  <p>the aim is to show just one part of a circle (or ellipse). Like the yellow area in the picture:</p>
