Even though I am adding a Foo to the List in the Controller Action, the Foo list in the Middleware is always empty. Why is this? I have tried changing the service registration

问题 so here's my situation: I have a .NET Core 2.0 web app which using Identity and Google auth. Claims retrieved from Google login are email, first name, last name, and domain.
