I just wasted two hours to figure out why the PushChannelURI in my Windows Phone Emulator has a PushChannelURI that is http://notificationserver.microsoft.com/AppKey…… but usually it should be something like https://db5.notifiy.windows.com/?token=…..
When this PushChannelURI is detected and you’re trying to send something to that URI, you would get an error, that this servername is not resolvable. The answer is simple: You have the Notifications-Simulation activated in your Emulator. Disable it, reinstall the app on the Emulator and your will have a regular Channel URI for the WNS back.
