ASP提供程序項目在Azure環境中失敗

Question

我最近在將新Azure應用程序部署到新服務器時發生了一個奇怪的錯誤。我正在使用ASP提供程序（由Microsoft提供的Azure SDK代碼示例）。不管多少次上傳，我都會收到這個醜陋的消息。請幫忙！

Answer 1

的優點與這些樣品是，提供代碼，這樣你就可以得到一般在什麼地方出了錯一探究竟。我看了一下，得到這個錯誤的最可能原因是會話狀態提供程序的配置有錯誤（它可能指向錯誤的帳戶），或者表和容器不存在於該帳戶。

有可能沒有會話對象可用，但我覺得不太可能。

話雖如此，表存儲會話提供程序是not suitable for releasing in a production environment。您使用SQL Server session provider或A pp Fabric cache session provider要好得多。

Answer 2

是AppFabric Cache由微軟正式發佈和支持。這個鏈接對教程很有幫助：http://msdn.microsoft.com/en-us/gg457897 但是，使用這種方法還有一個額外的計費方面，而Tablestoragesession提供程序使用BlobStorage，它是花生。
