Then when the app starts up again, you just use that from/to time when reconstructing the timer. Likewise, … Read more

I’m not sure why you get the results you get but it should work fine when the background is transparent (i.e. you explicitly set it to Brushes.Transparent, either through XAML or code). If it is null, WPF will not include it in hit testing, and thus it won’t be eligible for mouse events. See e.g. … Read more
If your app is in suspended state the applicationWillTerminate will never get called regardless who killed the app iOS or user. Your applicationWillTerminate will only call when your app is in background and it gets killed (either by iOS or user) the term background means that it is running in background not in suspended state. … Read more
