Receive WNS push notfication on Windows phone silverlight 8.1

I have windows phone 8.1 silverlight application where I want to receive Notfications using the new framework, WNS.

I have in the package.appxmanifest: <identity name="4657xxxxxxx" publisher="CN=xxxxx" version="1.0.0.0"/> and added it to the Mobile Service Hub.

For this I have removed old references to MPNS usings, and added the following for WNS:

using Windows.UI.Notifications;

using Windows.Networking.PushNotifications;

using Windows.UI.StartScreen;

This resulted in a new way of getting the channelURI:

 public static PushNotificationChannel CurrentChannel { get; private set; }

    public async static Task<bool> UploadChannel()
    {
        bool newChannel = false;
        var channel = await Windows.Networking.PushNotifications.PushNotificationChannelManager.CreatePushNotificationChannelForApplicationAsync();
        var settings = Windows.Storage.ApplicationData.Current.LocalSettings.Values;
        object oldChannel;
        settings.TryGetValue("channelURI", out oldChannel);
        if ((oldChannel as PushNotificationChannel).Uri != CurrentChannel.Uri)
        {
            settings.Add("channelURI", CurrentChannel);
            newChannel = true;
        }
        try
        {
            await App.MobileService.GetPush().RegisterNativeAsync(channel.Uri);
        }
        catch (Exception exception)
        {
            CurrentChannel.Close();
            HandleRegisterException(exception);
        }

        CurrentChannel.PushNotificationReceived += CurrentChannel_PushNotificationReceived;
        return newChannel;
    }
    private static void HandleRegisterException(Exception exception)
    {
        MessageBox.Show("error - retry pushchannel");
    }

Additionally I removed the ID_CAP_PushNotification based on microsofts update info I do not get a channel I get an error:

The application does not have the cloud notification capability. (Exception from HRESULT: 0x803E0110)

solution Searched for the error and found this link, This can be solved as stated in the answer below by accessing package.appxmanifest and enable Internet (Client & Server).

ERROR 2 Then it the UploadChannel()function should work. However the Register API call await App.MobileService.GetPush().RegisterNativeAsync(channel.Uri); results in an error on the server:

Message='Could not register with the 'mpns' platform. Error received: 'Unsupported channel uri: 'https://db3.notify.windows.com . . . .

The error makes sense but I have no idea on how to solve it.

Ekstra On the server I can subscribe with the URI, and receive notifications. But not on the client. Is this how it should be or?

Adding internetClient capability should resolve this error.

Creating a notification channel results in an WPN_E_CLOUD_INCAPABLE error Cause: Your app has not declared the Internet capability in its app manifest (package.appxmanifest). Fix: Ensure that your app manifest has declared Internet capability. In the Visual Studio manifest editor, you will find this option under the Capabilities tab as Internet (Client).
