title: Where is ConfigurationManager's namespace?
body: <p>I've got a reference to <code>System.Configuration</code> - and <code>ConfigurationSettings</code> is found no problem - but the type or namespace '<code>ConfigurationManager</code>' could not be found!?</p>
  
  <p>I've read around - and it looks like it should belong to the same namespace as the <code>ConfigurationSettings</code> class.</p>
  
  <p>EDIT: Please take note - <strong>I've clearly said I have added a reference to System.Configuration</strong>. There's been 4 comments already about this.</p>
