    if (tester != null) {
    tester.Close();
    throw new ArgumentException("The task \"" + name + "\" already exists.");
    }
    try {
        object o;
            //Error Occrured at this below line of Code
        its.NewWorkItem(name, ref CTaskGuid, ref ITaskGuid, out o); 
        ITask iTask = (ITask)o;
