title: How to modify the ${stacktrace} layout renderer in NLog
body: <p>I started using <code>NLog.Interface</code> so that I can use an <code>ILogger</code> interface instead of the <code>Logger</code> class provided on <code>NLog</code> (mainly for <em>unit testing</em>)</p>
  
  <p>When I use <code>${stacktrace}</code>,  I get something like this:</p>
  
  <blockquote>
    <p>... => LoginViewModel.LogIn => LoggerAdapter.Info</p>
  </blockquote>
  
  <p>I'd like to remove the <code>LoggerAdapter.Info</code> part (which is included because <code>NLog.Interface</code> wrapps the <code>Logger</code> class inside <code>LoggerAdapter</code>).</p>
  
  <p>How could I do that?</p>
