问题
I have a MVC4 Application that spends debug process locally without enabling Register External site clients (like twitter , etc...) yet. And I'm Using custom membership user and role providers. But unfortunately when I browse the 'Manage' Page get this error:
Operation is not valid due to the current state of the object.
And the stack trace :
[InvalidOperationException: Operation is not valid due to the current state of the object.] Microsoft.Web.WebPages.OAuth.OAuthWebSecurity.VerifyProvider() +91 Microsoft.Web.WebPages.OAuth.OAuthWebSecurity.HasLocalAccount(Int32 userId) +41 Melk.Controllers.AccountController.Manage(Nullable

Please help to be aware. Thanks.
回答1:
VerifyProvider will throw if you are using the SimpleMembershipProvider and it is not yet initialized, or if the provider does not inherit from ExtendedMembershipProvider.
If you are using WebSecurity out of the box, you need to make sure WebSecurity.InitializeDatabaseConnection is called first.
If you are using custom providers, make sure they are inheriting from ExtendedMembershipProvider (or SimpleMembershipProvider), otherwise you cannot use this function.
