Issue Creating Scheduled Toast Notifications

[derrickberg-dev]

Hello,

Could you test creating scheduled toast notifications without ever calling the CreateToastNotifier.Show() function?

If my app just creates scheduled toast notifications, it doesn't seem to work. One thing I tested was creating a build that creates notifications immediately using .show(), then replacing it with the one that uses AddToSchedule and then it starts working. There must be something that .show() is doing that AddToSchedule isn't, because until I call show() I never see my app in the Notification & Actions section of the Windows Settings. But, I don't see anything in the documentation on scheduled notifications that indicate this....

https://github.com/MicrosoftDocs/windows-uwp/blob/docs/windows-apps-src/design/shell/tiles-and-notifications/scheduled-toast.md

Doesn't work...

            var toast = new ScheduledToastNotification(toastContent.GetXml(), DateTime.Now.AddSeconds(5));
            DesktopNotificationManagerCompat.CreateToastNotifier().AddToSchedule(toast);

Will work...

                ToastNotification toast = new ToastNotification(toastContent.GetXml());
                DesktopNotificationManagerCompat.CreateToastNotifier().Show(toast);

                var toast = new ScheduledToastNotification(toastContent.GetXml(), DateTime.Now.AddSeconds(5));
                DesktopNotificationManagerCompat.CreateToastNotifier().AddToSchedule(toast);

I can build a version that creates 1 notification using .show() then delete it and replace it with the version that only uses .AddToSchedule() to create notifications and everything works.

What does calling .show() do in the background that .AddToSchedule() isn't doing? I see that using .show() winds up putting my app in the Notifications & Actions, where .AddToSchedule() never would.

Hey @andrewleader, I noticed you have a repo for testing toast notifications https://github.com/andrewleader/NotifTestApps

Got any ideas? Have you tested ScheduledToastNotifications before?
