MVC4 OAuth HasLocalAccount方法抛出InvalidOperationException

我有一个MVC4应用程序，它在本地花费调试过程而不启用Register External站点客户端（如twitter等）。 我正在使用自定义成员资格用户和角色提供程序。 但不幸的是，当我浏览“管理”页面时出现此错误：

由于对象的当前状态，操作无效。

并且堆栈跟踪：

请大家注意一下。 谢谢。

如果您正在使用SimpleMembershipProvider并且尚未初始化，或者提供程序未从ExtendedMembershipProviderinheritance，则VerifyProvider将抛出。

如果您正在使用WebSecurity，则需要确保WebSecurity.InitializeDatabaseConnection调用WebSecurity.InitializeDatabaseConnection 。

如果您使用自定义提供程序，请确保它们inheritance自ExtendedMembershipProvider （或SimpleMembershipProvider ），否则您将无法使用此function。
