An Application using SimpleMembership (as the MVC template internet application of VS 2012) and another application that uses ClaimsPrincipal with FederatedAuthetication.
Some One has experience on the authentication an authorization process using SimpleMembership and use FederatedAuthetication since the step:
a) When Login use websecuroty.Login (from SimpleMembership)
or
b) use FederatedAuthentication.SessionAuthenticationModule.WriteSessionTokenToCookie
where is the place to join this both two SimpleMembership with System.Security.Claims
Thanks
You can use this approach to bridge both worlds
