title: Namespace change - Multiple types were found that match the controller named 'Home'
body: <p>I ran into the following problem after changing the namespace for my mvc project:</p>
  <blockquote>
  <p>Multiple types were found that match the controller named 'Home'. This can happen if the route that services this request ('{controller}/{action}/{id}') 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 'MapRoute' method that takes a 'namespaces' parameter.</p>
  <p>The request for 'Home' has found the following matching controllers:</p>
  <p><strong>oldns</strong>.Controllers.HomeController</p>
  <p><strong>newns</strong>.Controllers.HomeController</p>
  </blockquote>
