asp.net-mvc – MVC4 SimpleMemberhip’提供商遇到了未知错误.

我正在尝试使用sql Azure数据库使用SimpleMembership和MVC4.

我得到一个例外

The Provider encountered an unkNown error.

没有内部异常,在这行代码上：

WebSecurity.CreateAccount("[e-mail]","23iu$9835",false);

我的控制器上有这个过滤器

[InitializeSimpleMembership]

其中包含此InitializeDatabaseConnection

WebSecurity.InitializeDatabaseConnection("DefaultConnection","User","Id","Email",autocreateTables: false);

我已经仔细检查了我的连接字符串,它似乎工作正常.

由于异常没有提供有用的信息,因此我很难调试此问题.有没有人有任何想法,为什么我可能有这个问题,或指出我正在开始调试问题的正确方向？

编辑：这是完整的堆栈跟踪：

解决方法

试试这个

WebSecurity.createuserAndAccount("[e-mail]",false);
