title: What are Verbose Errors
body: <p>I came across the following in a WCF Service I was working on and at no point have I either coded this in or seen it there before.</p>
  
  <pre><code>#If DEBUG Then
      config.UseVerboseErrors = True
  #End If
  </code></pre>
  
  <p>What does this do and where could it have come from</p>
  
  <p>Note - no one else has access to my work.</p>
