title: Facebook error: Some of the aliases you requested do not exist: access_token
body: <p>I'm using the C# Facebook library. With that i wanted to post something on my own wall, but i'm getting an error (as described in the title):</p>
  
  <blockquote>
    <p>(OAuthException) (#803) Some of the aliases you requested do not
    exist: access_token=438781769472xxxxxxxxxxxxxxxxxx</p>
  </blockquote>
  
  <p>This is what i'm doing in code:</p>
  
  <pre><code>FacebookClient facebookClient = new FacebookClient(myAccessToken);
  var args = new Dictionary&lt;string, object&gt;();
  args["message"] = "Test message";
  args["caption"] = "Caption";
  args["description"] = "Description";
  args["name"] = "Name";
  args["picture"] = "";
  args["link"] = "";
  
  // Not sure which one to use, but both give same error
  facebookClient.Post(appAccessToken+"/feed", args);
  //facebookClient.Post(appAccessToken, args);
  </code></pre>
  
  <p>Anyone any idea what the problem might be and how i can solve this??</p>
