Facebook C# SDK MVC3 APP Not posting on Wall

I am using the latest SDK of Facebook C# SDK i.e. 5.0.9 Beta I had one Text box in page in button which suppose to post the text in the users Wall. But the problem is when I am clicking on Button the page get redirected to something like http://localhost:5000/facebookredirect.axd?code=JU1q_vSj13WRn1wIjHjCZRF5iDy_xvkFUppxADeS0F0.eyJpdiI6InJwejVVWXpJY1RqV0VaY1JjTl92ZGcifQ.KSa0B1ax1qCZZ-K_oXLmAZR8lyknWDRY9ieWxuLIZqXedUzb1WQH_FrcMF98VO6U1Dk5KIo4dz4AMdBxtfrUUH0ucgOoPC6_7Zb03WsIgY2fF84L-0s3A7m3f971sJUS4nQyRGDZ_-8oPuO0K0dTPg&state=eyJyIjoiaHR0cDovL2FwcHMuZmFjZWJvb2suY29tL3Rlc3RhcHBfdGVzdGluZy9Ib21lL0Fib3V0P0xlbmd0aD0zIn0

and then again redirected to my apps URL in between I am not getting any data in my controller the values are showing as null.

After analyzing HTTP call I found the content is 

<html><head><script type="text/javascript">

top.location = "http://www.facebook.com/dialog/oauth/?scope=user_about_me,friends_about_me,publish_stream&state=eyJyIjoiaHR0cDovL2FwcHMuZmFjZWJvb2suY29tL3Rlc3RhcHBfdGVzdGluZy9ob21lL0Fib3V0In0&client_id=218380811509677&redirect_uri=http://localhost:5000/facebookredirect.axd";

</script></head><body></body></html>

I am using Ajax but the Behavior is same for normal as well.

It Seems like Authorizing on every Call. Do I need to implement Oauth 2.0.

I am Using sample APP for the MVC3. Can anyone tell me whats going wrong?

Try this code 

public ActionResult Index()
        {
            var url = "http://www.facebook.com/v2.2/dialog/oauth/?scope=user_friends,read_friendlists,publish_actions,read_stream,read_insights,manage_pages,user_checkins,user_photos,read_mailbox,manage_notifications,read_page_mailboxes,email,user_videos,user_groups,offline_access,publish_actions,manage_pages&client_id=" + ConfigurationManager.AppSettings["ClientId"] + "&redirect_uri=" + ConfigurationManager.AppSettings["RedirectUrl"] + "&response_type=code";

            return Redirect(url);
        }

Call Back Url 

    public string AddFacebookAccount(string code)
    {
        string ret = string.Empty;
        string client_id = ConfigurationManager.AppSettings["ClientId"];
        string redirect_uri = ConfigurationManager.AppSettings["RedirectUrl"];
        string client_secret = ConfigurationManager.AppSettings["ClientSecretKey"];
        long friendscount = 0;
        try
        {
            FacebookClient fb = new FacebookClient();
            string profileId = string.Empty;
            Dictionary<string, object> parameters = new Dictionary<string, object>();
            parameters.Add("client_id", client_id);
            parameters.Add("redirect_uri", redirect_uri);
            parameters.Add("client_secret", client_secret);
            parameters.Add("code", code);
            JsonObject fbaccess_token = null;
            try
            {
                System.Net.ServicePointManager.SecurityProtocol = System.Net.SecurityProtocolType.Tls;
                fbaccess_token = (JsonObject)fb.Get("/oauth/access_token", parameters);

            }
            catch (Exception ex)
            {

                try
                {
                    fbaccess_token = (JsonObject)fb.Get("/oauth/access_token", parameters);
                }
                catch (Exception ex1)
                {
                    return "issue_access_token";
                }
            }

            string accessToken = fbaccess_token["access_token"].ToString();
            Session["AccessToken"] = accessToken;
            if (accessToken != null)
            {
                fb.AccessToken = accessToken;
                System.Net.ServicePointManager.SecurityProtocol = System.Net.SecurityProtocolType.Tls;
                dynamic profile = fb.Get("v2.2/me");
                dynamic friends = fb.Get("v2.2/me/friends");
                try
                {
                    Session["uid"] = profile.id;
                    friendscount = Convert.ToInt16(friends["summary"]["total_count"].ToString());
                }
                catch (Exception ex)
                {
                    Console.Write(ex.Message);
                }

            }
            //return new JavaScriptSerializer().Serialize(ret);
            return ret;
        }
        catch (Exception ex)
        {
            Console.WriteLine(ex.StackTrace);
            return "Something Went Wrong";
        }
    }

Post Text and Image Code

        public ActionResult ComposeMessageSend(string message)
        {
            System.Net.ServicePointManager.Expect100Continue = false;

That´s a typical occurrence , when you use FacebookAuthorizeAttribute from Facebook.Web.Mvc. At least, your response-code let me assume that the oauth-handshake didn´t work properly (although you got the "code", you forgot to get your "access_token" with it)

In case you´re using FacebookAuthorizeAttribute, check if you´re app-settings in the facebook-developer-app AND your web.config have the right canvas-url/ canvas-page inserted. (In your case, for testing, "http://localhost/" / "http://apps.facebook.com/yourappname")

Recently I read a post, which said you mustn´t use the Facebook.Mvc classes, because they provide example-code. see 1. Answer on this link
