Windows Push Notification Service (commonly referred to as Windows Notification Service or WNS) is a notification service developed by Microsoft for all devices running Microsoft Windows platforms. It allows for developers to send push data ("toast" and "tile" updates) to Windows and Universal Windows Platform applications which implement the feature. Designed as a successor to the Microsoft Push Notification Service, it was first supported on Windows 8 and subsequently on Windows Phone 8.1 upon its release.
The Windows Push Notification Service (WNS) was designed as a successor to the Microsoft Push Notification Service (MPNS), which was only supported natively on the Windows Phone 8 Operating System. Developers can still use the MPNS on apps that are installed on newer versions of Windows Mobile (Windows Phone 8 or Windows Phone 8.1), but only if the Windows application was already registered to use the MPNS and has been converted to a Microsoft Silverlight application and modified to re-target the new platform.
In 2015, Microsoft announced that the WNS would be expanded to utilize the Universal Windows Platform architecture, allowing for push data to be sent to Windows 10, Windows 10 Mobile, Xbox, as well as other supported platforms using universal API calls and POST requests.
During the 2015 Build keynote, Microsoft announced a Universal Windows Platform bridge that would allow Android and iOS software to be ported to Windows 10 Mobile and published to the Windows Store. In August 2015, A version of the Microsoft Android bridge toolset was reported to be leaked and available on the internet along with its documentation. The leaked toolset required developers to register and use the WNS to send notification data to ported applications, and would not allow for Google Cloud Messaging to be used instead. Microsoft later discontinued the Android bridge project in favor of continuing support for iOS application porting instead.
