not able to logout from facebook using facebook c# sdk

Question

I am Using facebook C# SDK to connect to facebook from my mvc3 application. I am able to login but not able to logout. I used bellow code for logout

var oauth = new FacebookClient();

        var logoutParameters = new Dictionary<string, object>
              {
                  { "next", "http://localhost:8691" }
              };

        var logoutUrl = oauth.GetLogoutUrl(logoutParameters);

        return Redirect(logoutUrl.ToString());

This code always redirects me to facebook home page.

Answer 2

I have solved it. I just passed access token in logoutParameters.

Here is my action result code.

        public ActionResult LogOut(string accessToken)
    {
        var oauth = new FacebookClient();

        var logoutParameters = new Dictionary<string, object>
              {
                 {"access_token", accessToken},
                  { "next", "http://localhost:8691" }
              };

        var logoutUrl = oauth.GetLogoutUrl(logoutParameters);

        return Redirect(logoutUrl.ToString());
    }
