在带有和不带有SP1的Windows 7中，为什么在WPF中得到不同的线程行为？

Question

I have this multi-threaded WPF application and two different machines where I am testing it.

The first is a Windows 7 Professional, SP1 virtual machine on a VMware client. The second is a Win 7 Professional physical machine. No SP1.

On the first machine, the application runs normally, on the second machine the application outputs an AccessViolation exception when calling:

App.Current.Dispatcher.Invoke(() => { do stuff });

from a thread created in the following manner:

ThreadPool.QueueUserWorkItem( /* callback that calls the dispatcher */ );

Can you tell me why this is having a different behavior if the .Net framework version is the same? Is it because of the Service Pack? How can I solve this?

显然我在使用HookManager并没有在启动第二个之前关闭一个...为什么在虚拟机中而不是在物理机上工作超出了我的范围...
