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。它在我机器上的本地 IIS 实例上运行时工作，但一旦部署到 Azure，它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，然后每十分钟我得到第二个。证书可以很好地连接到 APNS 本身，实际上我已经收到了通过 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 的示例中所示。我是否需要另一个证书才能获得反馈服务或其他什么？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会导致此问题。

扩大到保留模式（如果你能得到一个），问题就消失了。
