title: The type or namespace name 'type/namespace' could not be found.. - Asp.Net - C#
body: <p>When I launch the website locally it works fine, however when I upload this to the server I get "The type or namespace name 'type/namespace' could not be found.." for my App_Code folder</p>
  
  <p>my ".aspx.cs" class</p>
  
  <pre><code>using XXXXXX.App_Code;
  </code></pre>
  
  <p>Any clues as to why?</p>
