title: using font file in wpf usercontrol
body: <p>I am using a WPF UserControl inside a Winforms form.  I have it working.  </p>
  
  <p>I would like the text that I use in the WPF UserControl to use a font that I have as a TTF.</p>
  
  <p>I do not know how to reference this TTF and have the control use it.  I am assuming I should load the TTF (this is not an installed font) in the UserControl and tell the control (a label) to use it but I only see reference to the font-family.</p>
