Overview:

• Why use PUSH Service
• Principles of the push notification service
• Usage Specification
• Message Type (raw notification, toast notification, tile notification)
• Timed tile update

First, why is push service used? The execution model of Windows Phone determines that only one third-party application can run on the frontend. Therefore, third-party applications cannot continuously pull data to the cloud in the background, microsoft provides the push notification service to send update notifications to third-party applications. The server initiates communications to reduce battery consumption,

So what is the process and principle of the push notification service:

• The WP device registers the PN service with the mpns and obtains a unique Uri,
• The WP device bar service URI is passed to the cloud service and registered
• When an update message occurs, cloud sends a notification to mpns.
• Mpns sends an update notification to the WP device.

Usage specification:

The wp7.0 version only supports up to 15 push notification services. Therefore, it is best to ask the user whether to use the push notification service and provide the user with the option of canceling the subscription.

Message Type:

• Raw notification: data in any format can be sent to applications.ProgramYou can process data as needed and receive messages only when the program is running.
• Toast notification: The sent data is specified as XML. If the program is running, the message is sent to the application. If the program is not running, a message is displayed in the toast message box,
• Tile notification: The sent data is specified as XML and will not receive messages when the program is running. Only when the program is pin to start will the updated data be sent to the tile of Start Screen, which contains three attributes: the background, title, and number of attributes have a fixed format and position. You can use these attributes, but not necessarily use them together,
