我在开发 Windows Phone 推送通知时遇到了问题。事件 ChannelUriUpdated根本没有触发。当我ConnectionStatusChanged按如下方式注册事件时：

  void pushChannel_ConnectionStatusChanged(object sender, NotificationChannelConnectionEventArgs e)
    {
        var state = e.ConnectionStatus;
    }

并且ConnectionStatusChanged是连续触发的。“状态”值交替连接和断开连接。

我使用代码：MSDN 推送通知示例代码

任何帮助将不胜感激。

如何为 Windows Phone 发送和接收 toast 通知

windows phone 的推送通知

使用下面的代码为我工作

 HttpNotificationChannel pushChannel;

            // The name of our push channel.
            string channelName = "ToastSampleChannel";

            InitializeComponent();

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

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

                // 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 toast 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()));

            }
        }
