title: Trying to update a Facebook event using the Graph API (Facebook C# SDK)
body: <p>I am trying to update the description of a Facebook event using the Facebook C# SDK. I have granted the following permission to my application: </p>
  
  <p>'publish_stream,email,manage_pages,user_events,create_event,rsvp_event'</p>
  
  <p>The event I am trying to update is one of my own events, so I believe I should be able to update it.</p>
  
  <p>In the code below "9999" is the event id of the event I created, and the event I am trying to amend:</p>
  
  <pre><code>Authorizer authorizer = new Authorizer();
  FacebookClient fbapp = new FacebookClient(authorizer.Session.AccessToken);
  Console.Write(fbapp.Get("9999"));
  dynamic parameters = new ExpandoObject();
  parameters.description = "the new description";
  fbapp.Post("9999", parameters);
  </code></pre>
  
  <p>The fbapp.Get works fine and returns the details of the event.</p>
  
  <p>The problem is with the Post method, this returns <code>(OAuthException) (#200) Permissions error</code></p>
  
  <p>Any ideas as to where I am going wrong?</p>
