    CalculationMode = CalculationMode.Automatic
};

var subtask1 = project.RootTask.Children.Add("1");
var subtask2 = project.RootTask.Children.Add("2");
project.TaskLinks.Add(subtask1, subtask2, TaskLinkType.FinishToStart);

project.RootTask.Children.Add("3");

// Display the critical path now
foreach (var task in project.CriticalPath)
{
    Console.WriteLine(task.Get(Tsk.Id) + "  " + task.Get(Tsk.Name));
    Console.WriteLine(task.Get(Tsk.Start));
    Console.WriteLine(task.Get(Tsk.Finish) + "\n");
}
