MVC5 Identity 2.0 Dependency Injection with Unity - dependency-injection

Question

I'm having trouble with Unity while trying to use DI with Identity 2.0. My project is MVC5 Wep Api2 REST services and AngularJS.
That's what I've tried so far: (note that: MyExtendedGroup : IdentityRole)
.RegisterType<MySecurityContext>("MySecurityCtx", new PerResolveLifetimeManager())
.RegisterType<IRoleStore<MyExtendedGroup, string>, RoleStore<MyExtendedGroup, string, IdentityUserRole>>("MyRolesStore", new InjectionConstructor(new ResolvedParameter<MySecurityContext>("MySecurityCtx")))
.RegisterType<IGroupAsyncService, GroupAsyncService>("groupAsyncService", new InjectionConstructor(new ResolvedParameter<IRoleStore<MyExtendedGroup>>("MyRoleStore")))
.RegisterType<GroupsAsyncController>(new InjectionConstructor(new ResolvedParameter<IGroupAsyncService>("groupAsyncService")))
I've been asked to post the controller's constructor. Here it is:
public GroupsAsyncController(IGroupAsyncService service)
{
_service = service;
}
That's the complete stacktrace:
HTTP/1.1 500 Internal Server Error
Content-Length: 5729
Content-Type: application/json; charset=utf-8

That's where I'm stuck. Thanks in advance for your help!
Update: basically I don't know how to use Unity DI on:
new UserManager(new UserStore(new MySecurityContext()));
or
new RoleManager(new RoleStore(new MySecurityContext()));
