我正在学习 MVC4 和实体框架的复数视觉教程。当我点击登录时我遇到了麻烦，用户和密码被正确保存在数据库中但是我得到了一个
Exception Details: System.InvalidOperationException: To call this method, the "Membership.Provider" property must be an instance of "ExtendedMembershipProvider".
当我尝试运行更新数据库时出错
这是我为数据库播种的方法
protected override void Seed(eManager.Web.Infrastructure.DepartmentDb context)
{
context.Departments.AddOrUpdate(d => d.Name,
new Department() { Name = "Engineering" },
new Department() { Name = "Sales" },
new Department() { Name = "Shipping" },
new Department() { Name = "Human Resources" });
if (Roles.RoleExists("Admin"))
{
Roles.CreateRole("Admin");
}
if (Membership.GetUser("rlemie") == null)
{
Membership.CreateUser("rlemie", "jumanji");
Roles.AddUserToRole("rlemie", "Admin");
}
}
}
这是我的网络配置

我的 Accountcontroller.cs 与复数教程中的不同，因为它使用 [InitializeSimpleMembership] 并且路由结构略有不同。
我更喜欢一个能解释我到底做错了什么的答案，因为我有一个解决方法可以解决它，但我不确定为什么，它会导致更多问题
