title: Type or namespace could not be found from App_code folder
body: <p>I have written a class called ArchivedFilesWrapper in the App_code folder of my project, however when I use this class in another file in a different folder i get error:</p>
  
  <p>The type or namespace name 'ArchivedFilesWrapper' could not be found (are you missing a using directive or an assembly reference?)</p>
  
  <p>I thought every page should be able to find classes that are contained within the same project, but I guess this is not the case. Can someone please tell me what using statement I need to have?</p>
  
  <p>Here is a snippet from my class:</p>
  
  <pre><code>using System;
  using System.Collections.Generic;
  using System.Linq;
  using System.Web;
  
  namespace EMCWebAdmin.App_Code
  {
      public class ArchivedFilesWrapper
      {
  </code></pre>
