title: Enum ToString appears as a number
body: <p>I have an enum</p>
  
  <pre><code>private enum TimeUnit
  {      
    Day,
    Month,
    Year
  }
  </code></pre>
  
  <p>And I'm populating a description with:</p>
  
  <pre><code>return string.Concat(unit, "(s)");
  </code></pre>
  
  <p>Where unit is a TimeUnit.  Most of the time this works fine and displays "Days(s)" however on a particular server it's displaying as "1(s)"</p>
  
  <p>What would cause this?</p>
