運行我的代碼，當我從我的本地機器連接到遠程數據庫中運行時，我得到異常下面出現了網絡相關的或特定於實例的錯誤一切正常。一旦部署到Webhost中，Simple Membeship Provider將引發下面的異常。我在其他控制器中使用相同的連接字符串，並沒有問題 - 連接到數據庫是好的。
這是我相信一行生成異常：
WebSecurity.InitializeDatabaseConnection（ 「MapEntities」， 「用戶配置」， 「用戶ID」， 「用戶名」，autoCreateTables：真）;
任何線索？非常感謝。

試着看看這個問題的一些想法。 http://stackoverflow.com/questions/5423278/ef-4-1-exception-the-provider-did-not-return-a-providermanifesttoken-string – 2013-03-06 02:48:33
感謝Brian的參考，但我不能讓它工作。關於該問題的奇怪之處在於同一數據庫/連接字符串上的其他實體可以工作。在我的本地機器上運行時，也是一樣。 – user2138011 2013-03-07 14:27:24
