MVC4 SimpleMemberhip '提供程序遇到未知错误。'

Question

我正在尝试使用 SQL Azure 数据库将 SimpleMembership 与 MVC4 结合使用。

我得到一个异常

The Provider encountered an unknown error.

没有内部异常，在这行代码上：

WebSecurity.CreateAccount("test@test.com", "23iu$9835", false);

我的控制器上有这个过滤器

[InitializeSimpleMembership]

里面有这个 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，我很难调试这个问题。有没有人知道我为什么会遇到这个问题，或者指出我开始调试问题的正确方向？

编辑：这是完整的堆栈跟踪：

试试这个

WebSecurity.CreateUserAndAccount("test@test.com", "23iu$9835", false);
