title: "Telerik" could not be found in global namespace
body: <p>Currently I am working on a ASP.NET web form project which is using Telerik Ajax Version 2015.2.623.45, I have added <strong>Telerik.Web.UI.dll</strong>, <strong>Telerik.Web.Design.dll</strong> into my project reference, but it keeps giving me errors saying </p>
  
  <p><code>The type or namespace name 'Telerik' could not be found in the global namespace (are you missing an assembly reference?)</code>  </p>
  
  <p>Here's some info of my project if that may helps:</p>
  
  <p>I am using .NET Framework 4, using Integrated Mode, </p>
  
  <p>the <code>dll</code>'s <code>Aliases</code> property is "global", and <code>Copy Local</code> property is True</p>
  
  <p>and my <code>web.config</code> contains following parts:</p>
  
  <p><div class="snippet" data-lang="js" data-hide="false">
  <div class="snippet-code">
  <pre class="snippet-code-js lang-js prettyprint-override"><code>&lt;controls&gt;
