title: ASP.NET MVC 5 doesn't show the error messages
body: <p>I have the following configuration in my "web.config":</p>
  
  <p></p>
  
  <pre><code>&lt;customErrors mode="Off"&gt;
  &lt;/customErrors&gt;
  
  &lt;compilation debug="true" targetFramework="4.5" /&gt;
  &lt;httpRuntime targetFramework="4.5" /&gt;
  &lt;pages&gt;
    &lt;namespaces&gt;
      &lt;add namespace="System.Web.Helpers" /&gt;
      &lt;add namespace="System.Web.Mvc" /&gt;
      &lt;add namespace="System.Web.Mvc.Ajax" /&gt;
      &lt;add namespace="System.Web.Mvc.Html" /&gt;
      &lt;add namespace="System.Web.Routing" /&gt;
      &lt;add namespace="System.Web.WebPages" /&gt;
    &lt;/namespaces&gt;     
  &lt;/pages&gt;
  </code></pre>
  
  <p></p>
  
  <p>If I have a mistake in my environment clearly shows errors, but when I upload it to windows azure shows the screen where it tells me that I have to put: </p>
  
  <pre><code>&lt;customErrors mode="Off" /&gt;
  </code></pre>
  
  <p>or</p>
  
  <pre><code>&lt;customErrors mode="RemoteOnly" redirectMode="~/file.html" /&gt;
  </code></pre>
  
  <p>and not shows errors. Is there some extra settings that I have to do in "web.config" in "ASP.NET MVC 5" to show the errors? </p>
