Yes...I started with the sample at http://channel9.msdn.com/learn/courses/WP7TrainingKit/WP7Silverlight/UsingPushNotificationsLab/Exercise-2-Introduction-to-the-Toast-and-Tile-Notifications-for-Alerts/
and skipped immediately down to "Task 3 – Processing Scheduled Tile Notifications on the Phone." After that I had to wait about 1 hour, leaving the emulator running on my desktop (1 hour is the minimum update interval, indicated as such for "performance considerations."
_shellTileSchedule = new ShellTileSchedule
{
Recurrence = UpdateRecurrence.Interval,
Interval = UpdateInterval.EveryHour,
StartTime = DateTime.Now - TimeSpan.FromMinutes(59),
RemoteImageUri = new Uri(@"http://cdn3.afterdawn.fi/news/small/windows-phone-7-series.png")
};
Note that setting the StartTime to DateTime.Now - 59 minutes did nothing. It still waited a full hour for its first update. I could not find any mechanism to perform "go to this URI and Update yourself NOW!", other than calling out to a web service that tickles a Tile Notification.
