c# - Configure Unity DI for ASP.NET Identity

Question

I'm using Unity successfully for all regular constructor injection such as repositories etc., but I can't get it working with the ASP.NET Identity classes. The setup is this:

public class AccountController : ApiController
{
    private UserManager<ApplicationUser> _userManager { get; set; }

    public AccountController(UserManager<ApplicationUser> userManager)
    {
        if (userManager == null) { throw new ArgumentNullException("userManager"); }
        _userManager = userManager;
    }

    // ...
}

with these configs for Unity:

unity.RegisterType<AccountController>();
unity.RegisterType<UserManager<ApplicationUser>>(new HierarchicalLifetimeManager());
unity.RegisterType<IUserStore<ApplicationUser>, UserStore<ApplicationUser>>(new HierarchicalLifetimeManager());

That's the same as other posts here for Autofac, Ninject e.g., but it doesn't work in my case. The error message is:

An error occurred when trying to create a controller of type 'AccountController'. Make sure that the controller has a parameterless public constructor. Manual creation works of course:

public AccountController()
    : this(new UserManager<ApplicationUser>(new UserStore<ApplicationUser>("Mongo")))
{
}

What's wrong?

UPDATE

As suggested by @emodendroket, shortening the code to this does the trick. No need for the Unity.Mvc package.

unity.RegisterType<IUserStore<IdentityUser>, 
  MyCustomUserStore>(new HierarchicalLifetimeManager());

and

public AccountController(UserManager<IdentityUser> _userManager,
  IAccountRepository _account)
{
    // ...

You also need to resolve the UserManager. The following is an example how you could do it with the UserManager and the RoleManager. In this sample I use the regular Unity 3 package instead of one of the derivates or bootstrappers (had some problems with them in the past).

AccountController

private readonly UserManager<ApplicationUser> _userManager;

private readonly RoleManager<IdentityRole> _roleManager;

public AccountController(IUserStore<ApplicationUser> userStore, IRoleStore<IdentityRole> roleStore)
{
  _userManager = new UserManager<ApplicationUser>(userStore);
  _roleManager = new RoleManager<IdentityRole>(roleStore);
}

Unity Bootstrapper

var accountInjectionConstructor = new InjectionConstructor(new IdentitySampleDbModelContext(configurationStore));
container.RegisterType<IUserStore<ApplicationUser>, UserStore<ApplicationUser>>(accountInjectionConstructor);
container.RegisterType<IRoleStore<IdentityRole>, RoleStore<IdentityRole>>(accountInjectionConstructor);
