Sending Push Notifications

Sending a toast or tile push notification is done by creating an XML envelope containing the notification information, converting it to a byte array, and then sending it via an HttpWebRequest to the MPNS.

Note

When sending a push notification, only the HTTP POST method is allowed. Using any other method such as GET, PUT, CREATE, or DELETE results in a 405 MethodNotAllowed response. Moreover, a ProtocolViolationException results when writing to the request Stream.

For testing purposes, however, the HTTP GET method can be used, and results in a 200 OK response regardless.

An example of a push notification URL is http://sn1.notify.live.net/throttledthirdparty/01.00/AAGvdLTQzLGqRZ0FRZRVT1GBAgoOs1kPAQAAAAQOMDAwAAAAAAAAAAAAAAA ...
