看到你所得到的错误后，这个问题似乎是事实，你叫WebSecurity初始化连接之前。

编辑抛出这样的错误文件：

public ActionResult Login(LoginModel model, string returnUrl) 
{ 
    if (!WebSecurity.Initialized) 
    { 
     WebSecurity.InitializeDatabaseConnection("DefaultConnection", "UserProfile", "UserId", "UserName", autoCreateTables: true); 
    }
