asp.net - 我*必须*在 MVC3 中覆盖多少 MembershipProvider

Question

到目前为止，我已经在我的 MVC3 应用程序中完成了所有身份验证工作，即通过我的 MemberRepository 类验证成员和创建成员。我现在想正式使用自定义 MembershipProvider。到目前为止，我只了解到我确实需要重写此类的 ValidateUser 方法，而且由于我没有使用登录控件，所以我什至不确定我是否一定要这样做。

覆盖方法，如 GetUser 和 CreateUser 为我的聚会带来了不请自来的类型，如 MembershipUser，我有一个精心制作的 Member 类。如果我不打算使用任何内置控件或管理工具，请有人帮我弄清楚我是否真的需要自定义成员(member)提供程序，如果我这样做，我是否应该将覆盖限制在绝对必要的范围内, 这是什么？

这是我为单元测试编写的一个。它尽可能少。
