title: How can I underline a single character in the Content of a Button in WPF?
body: <p>I have a number of buttons in my WPF window and I would like to have certain characters in the button contents underlined. </p>
  
  <p>I have tried using the "_" like "My_Content" to underline the C, however this does not appear until the user hits the Alt key, or has their local settings changed. Using &lt; Underline > within the Content property causes an error when I attempt to underline only part of the content like: </p>
  
  <p>Content="My&lt; Underline >C&lt; /Underline >ontent".</p>
  
  <p>I would prefer to set this in the XAML if possible. Any help would be appreciated.</p>
  
  <p>Thank You!</p>
