首先说明：如果没有进入调试模式的话，默认的调试窗口如下：
开始前的准备：
新建控制台程序DebugWindowDemo：
修改Program.cs 的代码为：
class S
{
public static void Main()
{
pcount = Environment.ProcessorCount;
Console.WriteLine("Proc count = " + pcount);
ThreadPool.SetMinThreads(4, -1);
ThreadPool.SetMaxThreads(4, -1);
t1 = new Task(A, 1);
t2 = new Task(A, 2);
t3 = new Task(A, 3);
t4 = new Task(A, 4);
Console.WriteLine("Starting t1 " + t1.Id.ToString());
t1.Start();
Console.WriteLine("Starting t2 " + t2.Id.ToString());
t2.Start();
Console.WriteLine("Starting t3 " + t3.Id.ToString());
t3.Start();
Console.WriteLine("Starting t4 " + t4.Id.ToString());
t4.Start();
Console.ReadLine();
}
static void A(object o)
{
B(o);
}
static void B(object o)
{
C(o);
}
static void C(object o)
{
int temp = (int)o;
Interlocked.Increment(ref aa);
while (aa < 4)
{
}
if (temp == 1)
{
// BP1 - all tasks in C
Debugger.Break();
waitFor1 = false;
}
else
{
while (waitFor1)
{
}
}
switch (temp)
{
case 1:
D(o);
break;
case 2:
F(o);
break;
case 3:
case 4:
I(o);
break;
default:
Debug.Assert(false, "fool");
break;
}
}
static void D(object o)
{
E(o);
}
static void E(object o)
{
// break here at the same time as H and K
while (bb < 2)

Debugger.Break();
Interlocked.Increment(ref bb);
