title: AspNetSession layout renderer not working
body: <p>I am using NLog for logging in my asp.net 4.5 website. I have used NLog 4.0. Now I need to use session variables in my logs. So i tries to use AspNetSession layout renderer. This layout renderer is included in Nlog.Web. I have added this dll and also under the extensions tag in NLog config file. But it gives the following error:</p>
  
  <blockquote>
    <p>ArgumentException: LayoutRenderer cannot be found: 'aspnet-session'</p>
  </blockquote>
  
  <p>I have also added <code>NLog.extended</code> dll and also under the extensions tag in NLog config file. But it also didn't help.</p>
  
  <p>Please let me know what should i do.</p>
