问题 When using Attribute Routing in ASP.Net MVC 5 you would call the command routes.MapMvcAttributeRoutes(); and then just add the Route() tag to the Controller/Actions you wanted to build routes to. I am now trying to do this in ASP.Net MVC 6 and have found many pages that show you how to do it, which is really no different than in MVC 5, but they don't show you where or how to register those routes. Does ASP.Net MVC 6 just due it for you automatically or is there an equivalent to routes

问题 The question: I call RoleManager.CreateAsync() and RoleManager.AddClaimAsync() to create roles and associated role claims. Then I call UserManager.AddToRoleAsync() to add users to those roles. But when the user logs in, neither the roles nor the associated claims show up in the ClaimsPrincipal (i.e. the Controller's User object). The upshot of this is that User.IsInRole() always returns false, and the collection of Claims returned by User.Claims doesn't contain the role claims, and the
