Windows Phone 8 Push Notification - Unsupported channel uri

So I'm trying to get the push notifications working with Azure and windows phone 8 but I get a Unsupported channel uri: 'http://s.notify....' exception. We got it working with android and ios but I have a problem with windows phone. So on the windows phone where doing first the call's like the code below. This gives me a Uri that looks like this:

http://s.notify.live.net/u/1/db3/HmQAAABvGpd1XkjaC-XkYBpLYRrzC_DuH5ahcYzhdl8bT38ZJwNhI7_RGjG2ggirG0P1LJ2e6QAYm0uslRnGqcaImzdq/cHYtZGV2ZWxvcC1tZXNzYWdlcw/7A7WUjse3k2tlLMokVXD6g/rJ4ipeALhkNuxmeeJAAdsrrKRhY

The way I got this code is with this code:

HttpNotificationChannel pushChannel;

        // Try to find the push channel.
        pushChannel = HttpNotificationChannel.Find(App.HubName);

        // If the channel was not found, then create a new connection to the push service.
        if (pushChannel == null)
        {
            pushChannel = new HttpNotificationChannel(App.HubName, App.ServiceName);

            // Register for all the events before attempting to open the channel.
            pushChannel.ChannelUriUpdated += new EventHandler<NotificationChannelUriEventArgs>(PushChannel_ChannelUriUpdated);
            pushChannel.ErrorOccurred += new EventHandler<NotificationChannelErrorEventArgs>(PushChannel_ErrorOccurred);

            // Register for this notification only if you need to receive the notifications while your application is running.
            pushChannel.ShellToastNotificationReceived += new EventHandler<NotificationEventArgs>(PushChannel_ShellToastNotificationReceived);

            pushChannel.Open();

            // Bind this new channel for Tile events.
            pushChannel.BindToShellToast();
        }
        else
        {
            // The channel was already open, so just register for all the events.
            pushChannel.ChannelUriUpdated += new EventHandler<NotificationChannelUriEventArgs>(PushChannel_ChannelUriUpdated);
            pushChannel.ErrorOccurred += new EventHandler<NotificationChannelErrorEventArgs>(PushChannel_ErrorOccurred);

            // Register for this notification only if you need to receive the notifications while your application is running.
            pushChannel.ShellToastNotificationReceived += new EventHandler<NotificationEventArgs>(PushChannel_ShellToastNotificationReceived);

            // Display the URI for testing purposes. Normally, the URI would be passed back to your web service at this point.
            System.Diagnostics.Debug.WriteLine(pushChannel.ChannelUri.ToString());
            MessageBox.Show(String.Format("Channel Uri is {0}", pushChannel.ChannelUri.ToString()));
        }

After that I send the pushChannel.ChannelUri to the server to create a backend registration of my device. The error (Unsupported channel uri) appears at the call:

var registrationDescription = await _hub.CreateOrUpdateRegistrationAsync(registration);

The registration comes from:

RegistrationDescription registration = new WindowsTemplateRegistrationDescription(request.Handle, request.Template);

The Handle is the request Uri I send to the server and the template is the xml template.

Now I don't know whats going wrong and am becoming a little bit crazy because of this error. Especially since the code works for android and ios but not for the wp8. I also tried with the PushNotificationChannelManager but it just crashes when it's doing the CreatePushNotificationChannelForApplicationAsync call.

Thanks in advance

Until WinPhone 8.0, the push notifications for that platform was done by the "MPNS" (Microsoft Push Notification System). On Windows Phone 8.1 there are now two options: if you're building the new universal or "store" version, you'd use the same version that is used for regular Windows Store apps (WNS - Windows Notification System). What you're doing is mixing up the two versions of the notification in the same code. When you create a notification channel using the HttpPushNotification class (from Microsoft.Phone.Notification namespace), you're using the MPNS registration. If this is the case, then you should not use the WindowsTemplateRegistrationDescription class; instead, use the MpnsTemplateRegistrationDescription one.

In case you are running your code in the phone simulator: The simulator does not support recieving Push messages - You will have to use a "real" phone.
