Windows Phone 7 Toast通知，前台有应用程序

Question

Quick question. I did this:

myChannel.ShellToastNotificationReceived += new EventHandler<NotificationEventArgs>(myChannel_ShellToastNotificationReceived);

So if I receive a toast notification while the application is in the foreground the myChannel_ShellToastNotificationReceived function should be called. In that function I have:

void myChannel_ShellToastNotificationReceived(object sender, NotificationEventArgs e)
{
    Dispatcher.BeginInvoke(() =>
    {
       ApplicationTitle.Text = "Toast Notification Message Received";
    });
}

The problem is that the function is never called and the ApplicationTitle is never changed.

Am I doing anything wrong?

I've found the problem...it seemed that the toast xml that was being sent was well enough formatted so the phone would receive it out of the app but not when it was inside it. Wrote the xml by "hand" and didn't use xmlWriter and worked.

string toastMessage = "<?xml version=\"1.0\" encoding=\"utf-8\"?>" +
        "<wp:Notification xmlns:wp=\"WPNotification\">" +
           "<wp:Toast>" +
              "<wp:Text1>" + title + "</wp:Text1>" +
              "<wp:Text2>" + message + "</wp:Text2>" +
           "</wp:Toast>" +
        "</wp:Notification>";
