Summary

This chapter looked at the advantages of push notification, and how it can be used to extend the battery life of the device.

The chapter began with an overview of push notification, starting with the three different types of push notifications: toast, tile, and raw notifications. The various types of channel errors that can occur during push notification were examined, and you saw how the phone’s battery level affects delivery of push notifications. The chapter also looked at cloud service authentication using X.509 certificates, and at how to update an application tile without tile notifications using shell tile schedules.

Finally, the chapter explored a stock ticker sample app that allows the user to enter a stock symbol into the phone, after which a cloud service periodically notifies the phone of stock price variations.
