我无法找到正确的 Unity 配置以使其与 MvcMembership 一起使用。

此时，我收到以下错误消息：

无法构造 Boolean 类型。您必须配置容器以提供此值。

这是我注册依赖项的代码：

    container.RegisterInstance<MembershipProvider>(Membership.Provider);

    container.RegisterType<IMembershipSettings,AspNetMembershipProviderSettingsWrapper>();
    container.RegisterType<IUserService, AspNetMembershipProviderWrapper>();
    container.RegisterType<IPasswordService, AspNetMembershipProviderWrapper>();
    container.RegisterType<IRolesService, AspNetRoleProviderWrapper>();
    container.RegisterType<ISmtpClient, SmtpClientProxy>();
    container.RegisterType<IRegistrationSettings, RegistrationSettings>();

这是我的堆栈跟踪：

例外是： InvalidOperationException - 无法构造 Boolean 类型。您必须配置容器以提供此值。

我通过使用上述构造函数上方的以下属性指定用于 UserAdministrationController 的构造函数来解决此问题：

[Microsoft.Practices.Unity.InjectionConstructor]

当构造函数重载时，Unity 会尝试使用具有最多参数的构造函数。使用 InjectionConstructor 属性，我强制它使用带有零参数的构造函数。
