You can create a check which will check locally if user has rated the application earlier or not. Take a look at following code:

public void reviewfunction()
    {
        //For Windows phone 8 app
        var settings = IsolatedStorageSettings.ApplicationSettings;

        //For windows phone 8.1 app or universal app use the following line of code
        //var settings = Windows.Storage.ApplicationData.Current.LocalSettings;

        //set the app name
        string Appname = "My app";

        if (!settings.Contains("review"))
        {
            settings.Add("review", 1);
            settings.Add("rcheck", 0);
        }
        else
        {
            int no = Convert.ToInt32(settings["review"]);
            int check = Convert.ToInt32(settings["rcheck"]);
            no++;
            if ((no == 4 || no == 7 || no % 10 == 0) && check == 0)
            {
                settings["review"] = no;
                MessageBoxResult mm = MessageBox.Show("Thank you for using this application.\nWould you like to give some time to rate and review this application to help us improve", Appname, MessageBoxButton.OKCancel);
                if (mm == MessageBoxResult.OK)
                {
                    settings["rcheck"] = 1;
                    MarketplaceReviewTask rr = new MarketplaceReviewTask();
                    rr.Show();
                }
            }
            else
            {
                settings["review"] = no;
            }
        }
    }
