title: In WPF, what are the differences between the x:Name and Name attributes?
body: <p>Sometimes it seems that the <code>Name</code> and <code>x:Name</code> attributes are interchangeable.</p>
  <p>So, what are the definitive differences between them, and when is it preferable to use one over the other?</p>
  <p>Are there any performance or memory implications to using them the wrong way?</p>
