title: COM Interface Guid
body: <p>I'm not much into COM interfaces, so i have a small question, say I have this code:</p>
  
  <pre><code>[Guid("148BD528-A2AB-11CE-B11F-00AA00530503"), 
   InterfaceType(ComInterfaceType.InterfaceIsIUnknown)]
  internal interface IEnumWorkItems {
      [PreserveSig()]
      int Next([In] uint RequestCount, [Out] out System.IntPtr Names, 
                         [Out] out uint Fetched);
      void Skip([In] uint Count);
      void Reset();
      void Clone([Out, MarshalAs(UnmanagedType.Interface)] 
                            out IEnumWorkItems EnumWorkItems);
  }
  </code></pre>
