\"SimpleMembership\", we\'re told, is the future of asp.net membership / role management. The MVC4 \"Internet Application\" template implements Account management using Simp
Accepted answer is not correct, that is not N-Tier. The membership data access and business logic are occurring in the same layer. Just because code is in a different assembly doesn't mean it isn't in the same layer.
Without some kind of transport mechanism to the data access layer, this is not N-Tier.
The solution is to inherit and override the WebMatrix SimpleMembershipProvider class such that its data access calls can be performed on a separate host.
I recommend using dotPeek to look at SimpleMembershipProvider so you know what to do in your overrides.
