    class Program
    {
        static void Main(string[] args)
        {
            Application app = new Application();
            TaskInfos tInfos = app.TaskInfos;

            if (tInfos.Contains("Data Flow Task"))
            Console.WriteLine("The application contains the Data Flow Task");
        }
    }
