Hello every body I have figured what is the problem and thanks prabir for your help the problem was I was a new in Facebook application development the problem was i want to make more than one application use the same solution so there is no need the settings in the config file because i set them problematically on the run time and here is the peace of code i am using :

I create a class the implement ifacebookapplication whisch contain this method :

 private IFacebookApplication GetCurrent()
        {       
            RouteData UrlData = HttpContext.Current.Request.RequestContext.RouteData;

            FaceBookSettings fbSettings = FaceBookSettingsManager.GetFaceBookSettingsByAppId((string)UrlData.Values["appId"]);
            var FBApp = new DefaultFacebookApplication();

            FBApp.AppId=fbSettings.AppId;
            FBApp.AppSecret=fbSettings.AppSecret;
            FBApp.CancelUrlPath=fbSettings.CancelUrlPath;
            FBApp.CanvasPage=fbSettings.CanvasPage;
            FBApp.CanvasUrl=fbSettings.CanvasUrl;
            FBApp.SecureCanvasUrl=fbSettings.SecureCanvasURL;
            FBApp.SiteUrl=fbSettings.SiteUrl;
            FBApp.UseFacebookBeta = fbSettings.UseFacebookBeta;

            return FBApp;
        }

and within my application start I st this :

   FacebookApplication.SetApplication(new FaceBookApplicationSettings());

and within my config file i am not setting any configuration except :

  <httpHandlers>
      <add verb="*" path="facebookredirect.axd" type="Facebook.Web.FacebookAppRedirectHttpHandler, Facebook.Web" />
    </httpHandlers>

that is all thanks alot :)
