title: The type or namespace name 'AjaxControlToolKit' could not be found (are you missing a using directive or an assembly reference?)
body: <p>I am currently working on Asp.Net with <code>AjaxControlToolkit</code>
  I have search many articles regarding this, but couldn't find a proper answer.
  I have even gave a  reference by right clicking on BIN Folder to the <code>AjaxControlToolKit.dll</code> where is saved and in my project's bin folder there is  <code>AjaxControlToolKit.dll</code> and <code>Ajaxmin.dll</code> but problem still persists.</p>
  
  <p>How to solve this problem? Can any one help please?
  Thank you in advance !</p>
