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);
