[MonoTouch] Invo

2011-08-11 Thread Matteo Polito 
Hi,

why if I execute this code my app freeze? To use again my app I need to
close and reopen it. I've used this code(threadpool and ManualResetEvent)
because I need to execute a method on thread but I need to wait its
completion.

var resetEvent = new ManualResetEvent(false);
ThreadPool.QueueUserWorkItem(
arg =
{
this.InvokeOnMainThread(delegate
{
UIAlertView _AlertView = new UIAlertView(Test, Test, null, OK, null);
_AlertView.Show();
});
resetEvent.Set();
});
resetEvent.WaitOne();


Do you know why?

Someone can help me?

The main thread is blocked by resetEvent.WaitOne(), and
InvokeOnMainThread is probably crashing because of this.
