Question

我想访问SimpleMembershipProvider的全部功能，例如ValidateUser方法。

因此根据其documentation我不应该调用WebSecurity.InitializeDatabaseConnection()进行初始化，而是启用标准成员资格和角色提供程序。

我的问题是：如何初始化SimpleMembershipProvider类

最后：可以访问SimpleMembershipProvider

的完整功能

或者如果有更好的解决方案，谢谢

如何初始化SimpleMembershipProvider类

如果查看默认的ASP.NET MVC 4 Internet应用程序模板，AccountController将使用[InitializeSimpleMembership]属性进行修饰。这是在这个样本中初始化的方式。这意味着您可以在通过帐户控制器之后使用它，而不是之前。如果您想在进行身份验证之前使用您的会员资格提供商，则可以使用Application_Start方法执行相同操作。
