Windows Store App Push Notifications via Azure Service Bus

问题

I'm trying to send a push notification to my Windows Store App developed in my laptop using VS 2013 Express. It's been few days now but I cannot figure out why I get "The Token obtained from the Token Provider is wrong" error. I use Windows Azure Notification Bus for this purpose. I use VS Server Explorer to send test notifications. I can see my laptop is being registered as a device in the Device Registration tab too. I tried the Azure portal as well, but the same error. However, when I try to connect to Service Bus Explorer 2.4.3.0 providing the connection string it throws below error. <21:47:14> Exception: The remote server returned an error: (401) Unauthorized. Manage claim is required for this operation..TrackingId:c0c4fea2-08bc-4def-964c-ec6e690b7551_G45,TimeStamp:10/12/2014 4:17:11 PM. Method b__7e: retry 2 of 10.

FYI: I'm following below article step by step. http://azure.microsoft.com/en-us/documentation/articles/notification-hubs-windows-store-dotnet-get-started/

Please help me. Thank you. Mahesh

Looks like token is just expired. Make sure you obtain token each time application starts. In terms of the article you refer it means you should call method InitNotificationsAsync() to do it. Here is that method:

private async void InitNotificationsAsync()
{
    var channel = await PushNotificationChannelManager.CreatePushNotificationChannelForApplicationAsync();

    var hub = new NotificationHub("<hub name>", "<connection string with listen access>");              
    var result = await hub.RegisterNativeAsync(channel.Uri);

    // Displays the registration ID so you know it was successful
    if (result.RegistrationId != null)
    {
        var dialog = new MessageDialog("Registration successful: " + result.RegistrationId);
        dialog.Commands.Add(new UICommand("OK"));
        await dialog.ShowAsync();
    }

}
