WMicrosoft Push Notification Service is a mobile service developed by Microsoft. It allows for developers to send push data from servers to Windows Phone applications. The MPNS is natively supported on applications that target the Windows Phone 8 Operating System. Microsoft announced the Windows Notification Service for Windows 8 and Windows Phone 8.1 in 2011, effectively replacing the MPNS with this service. The MPNS can be used on applications that are installed on Windows Phone 8.1 if the source code is migrated to a Microsoft Silverlight application, modified to target Windows Phone 8.1, and was already registered to use the MPNS before the upgrade.
