SQLTableDependency does not work after Restore the Database

Dear I was practicing receiving notifications of changes in the Tables with SQLTableDependency in a testing environment. I did not have any problem, but then when I took the database to a production environment (Backup and then Restore) it did not work anymore.

I saw that I regenerated the SQLTableDependency's Objects again, but I still do not receive notifications.

The documentation says that:

  

"Database Backup and Restore: restoring SqlTableDependency's db   objects, it does not work. "

And apparently the problem is there.

I also tried without positive results:

• Attaching the Database.

• Manually deleting SQLTableDependency's Objects

The Code used is:

    class Program
{
    private static string _con = "Data Source=.;Initial Catalog=Dependency;User ID=Usuario;Password=XXXXXXXX";
    static void Main(string[] args)
    {
        using (var dep = new SqlTableDependency<Spoolers>(_con, tableName: "Spoolers"))
        {
            dep.OnChanged += Changed;
            dep.OnError += Error;
            dep.OnStatusChanged += OnStatusChanged;
            dep.TraceLevel = TraceLevel.Verbose;
            dep.TraceListener = new TextWriterTraceListener(Console.Out);
            dep.Start();

            Console.WriteLine("Press a key to exit");
            Console.ReadKey();

            dep.Stop();
        }            
    }

    static void OnStatusChanged(object sender, StatusChangedEventArgs e)
    {
        Console.WriteLine(e.ToString());
    }

    public static void Changed(object sender, RecordChangedEventArgs<Spoolers> e)
    {
        var changedEntity = e.Entity;

        Console.WriteLine("DML operation: " + e.ChangeType);
        Console.WriteLine("ID: " + changedEntity.Id_Spooler);
        Console.WriteLine("Id_Estado_Spooler: " + changedEntity.Id_Estado_Spooler);
        Console.WriteLine("Fecha_Hora_Estado_Spooler: " + changedEntity.Fecha_Hora_Estado_Spooler.ToShortTimeString());
    }
    public static void Error(object sender, ErrorEventArgs e)
    {
        Exception ex = e.Error;
        throw ex;        
    }
}

Is there any way to "reconnect" the program with the SQLTableDependency's Objects created ?. They have a common nomenclature.
