Question

我最近在新服务器中部署Azure应用程序时遇到了一个奇怪的错误。我正在使用ASP提供程序（由Microsoft提供的Azure SDK代码示例）。无论上传多少，我都会收到这个大丑陋的消息。请帮忙！

Answer 1

是的，AppFabric Cache正式发布并得到微软的支持。这个链接对教程很有帮助：http://msdn.microsoft.com/en-us/gg457897 但是，使用这种方法还有一个额外的计费方面，而Tablestoragesessionprovider使用BlobStorage，即花生。

这些示例的优势在于提供了代码，因此您通常可以仔细查看出现的问题。我看了一下，你得到这个错误的最可能的原因是会话状态提供程序的配置有错误（它可能指向错误的帐户）或者表和容器不存在于那个帐户。

有可能没有可用的会话对象，但我发现这不太可能。

话虽如此，表存储会话提供程序是not suitable for releasing in a production environment。无论是使用SQL Server session provider还是使用A pp Fabric cache session provider，你都会好得多。
