ThreadPool.QueueUserWorkItem worker thread quit quietly?

Hello All,

I met a strange behavior with the system threadpool. The worker thread seems
to quit in the middle of processing. Here is the code: I could see the step 1
is finished but step 2 is not finished. There was no exception. Any thoughts?
{
...
ThreadPool.QueueUserWorkItem(new WaitCallback(Process_Data), myObj)
...
}

static void Process_Data(object Data)
{
...
try
{
//step 1
...
//step 2
...
}
catch ()
{
...
}
}

In the 1.1 version of the framework if you have an exception occur on a
thread poolthread then it will be swallowed without any notification, this is
not the same for the 2.0 version of the framework, see:

Hi Mark,

Thanks for reply. If there is an exception in the threadpool thread, shall
the Try...Catch catch the exception? I have the Try Catch around the callback
function.
