I have noticed, that some wp8 apps (e-mail app etc.) updates their live tiles immediately when internet connection is available. Is there any way how to achieve same thing without push notifications using event (Microsoft.Phone.Net.NetworkInformation.NetworkStatusChanged)? I know that there are Periodic tasks and Resource intensive tasks, but they run only once per 30 minutes. Background agent downloads small amount of data, and show notification if data are not equal with data from foreground app.
