MVC4 OAuth HasLocalAccount方法拋出InvalidOperationException

Question

我有一個MVC4應用程序，本地調試進程沒有啓用註冊外部網站客戶端（如Twitter等等）。我使用自定義成員資格用戶和角色提供者。但不幸的是，當我瀏覽了「管理」頁面出現此錯誤：

Operation is not valid due to the current state of the object.

而且堆棧跟蹤：

請幫忙注意。謝謝。

VerifyProvider如果您使用的是SimpleMembershipProvider並且尚未初始化，或者提供程序沒有從ExtendedMembershipProvider繼承，則會拋出。

如果您使用的是開箱即​​用的WebSecurity，您需要確保首先調用WebSecurity.InitializeDatabaseConnection。

如果您使用自定義提供程序，請確保它們從ExtendedMembershipProvider（或SimpleMembershipProvider）繼承，否則您將無法使用此功能。
