title: How do I make a UWP custom (i.e. templated) button control with accessibility support
body: <p>I've created a UWP custom (i.e. templated) control. How do I make it accessible?</p>
  
  <p>Right now when I try to use it with the Windows Narrator tool it behaves poorly. Sometimes Narrator doesn't see it at all, and sometimes it drills down into the tree of UI elements within my control when I don't want it to.</p>
  
  <p>Initially I thought I just needed to set some of the Automation attached properties, but they had no apparent effect.</p>
