title: No Definition for Plugin in XSockets.net
body: <p>I am working on a RTC Project in ASP.net and using XSockets.net for signalling purpose in VS 2013. But as I install XSockets.net 4.1.0 and try to create Xsockets.Net.BootStrapper class under App_Start folder it comes up with an error that Project doesn't contain definition for Plugin.</p>
  
  <p><strong>BootStrapper.cs:</strong></p>
  
  <pre><code>using System.Web;
  using XSockets.Core.Common.Socket;
  [assembly: PreApplicationStartMethod(typeof(RTC.App_Start.XSockets), "Start")]
  namespace RTC.App_Start
  {
      public static class XSockets
      {
          private static IXSocketServerContainer container;
          public static void Start()
          {
              container = XSockets.Plugin.Framework.Composable.GetExport&lt;IXSocketServerContainer&gt;();
              container.Start();
          }
      }
  }
  </code></pre>
