title: Facebook c# Access user wall information
body: <p>I want to get the wall information of a user and analyse it. It is a public information but when I try I will always get a <code>403</code> error.</p>
  
  <p>Why?</p>
  
  <ol>
  <li>Do I need to register my app in facebook even though I am not posting any info?  </li>
  <li>Do it need login infomation? If yes: How to provide that information?</li>
  </ol>
