title: Multiple types were found that match the controller named 'Account'. MVC 4 & using RouteConfig.CS
body: <p>I currently have 2 projects in same folder.
  Main</p>
  
  <ul>
  <li>Project1</li>
  <li>Project2</li>
  </ul>
  
  <h3>Problem:</h3>
  
  <p>Multiple types were found that match the controller named <strong>Account</strong>. This can happen if the route that services this request <code>('{controller}/{action}/{id}')</code> does not specify namespaces to search for a controller that matches the request. If this is the case, register this route by calling an overload of the <code>MapRoute</code> method that takes a <code>namespaces</code> parameter.</p>
  
  <p>The request for <code>Account</code> has found the following matching controllers:</p>
  
  <blockquote>
    <p>Project1.Controllers.AccountController</p>
    
    <p>Project2.Controllers.AccountController</p>
  </blockquote>
  
  <p>I using Foundation 4.
  Thanks advance</p>
