我有一个ASP.Net MVC4网站，在Azure上运行一个简单的Web服务，为我们的移动应用程序提供推送通知服务。它在我的机器上的本地IIS实例上运行时有效，但是一旦部署到Azure，它就会工作一段时间然后停止。在PushSharp无法连接到Apple的反馈服务后，它似乎可能会停止。最初我得到第一个堆栈跟踪，然后每隔十分钟得到第二个跟踪。证书可以很好地连接到APNS本身，实际上我收到了通过Azure Web服务发送的测试推送通知。我正在从文件中加载证书，如PushSharp的示例所示。我是否需要其他证书才能获得反馈服务？ 有没有其他人有类似的设置工作？

这似乎是相关的。 https://github.com/Redth/PushSharp/issues/49
Azure网站的免费或共享模式将导致此问题。
扩展到保留模式（如果可以获得），问题就会消失。
