Register IAuthenticationManager with Unity

Question

I use Unity for Dependencies Injection and using Identity Provider to control user login, registration, email confirmation, etc.

When I try to register a user, I have this problem:

The current type, Microsoft.Owin.Security.IAuthenticationManager, is an interface and cannot be constructed. Are you missing the display type?

I do not know how to register this interface (IAuthenticationManager) in a Unity container.

I tried to register an interface with this code, but if I put it, I have another problem:

Not registered IUserTokenProvider.

container.RegisterType<HttpContextBase>( new InjectionFactory(_ => new HttpContextWrapper(HttpContext.Current))); container.RegisterType<IOwinContext>(new InjectionFactory(c => c.Resolve<HttpContextBase>().GetOwinContext())); container.RegisterType<IAuthenticationManager>( new InjectionFactory(c => c.Resolve<IOwinContext>().Authentication)); 

I added the application code (if I do not use Unity, everything works fine):

AccountController

 private IAuthenticationManager AuthenticationManager { get { return HttpContext.GetOwinContext().Authentication; } } 

IdentityConfig.cs

 public class ApplicationUserManager : UserManager<ApplicationUser> { public ApplicationUserManager(IUserStore<ApplicationUser> store) : base(store) { } public static ApplicationUserManager Create(IdentityFactoryOptions<ApplicationUserManager> options, IOwinContext context) { var manager = new ApplicationUserManager(new UserStore<ApplicationUser>(context.Get<ApplicationDbContext>())); // Configure validation logic for usernames manager.UserValidator = new UserValidator<ApplicationUser>(manager) { AllowOnlyAlphanumericUserNames = false, RequireUniqueEmail = true }; // Configure validation logic for passwords manager.PasswordValidator = new PasswordValidator { RequiredLength = 6, RequireNonLetterOrDigit = true, RequireDigit = true, RequireLowercase = true, RequireUppercase = true, }; // Configure user lockout defaults manager.UserLockoutEnabledByDefault = true; manager.DefaultAccountLockoutTimeSpan = TimeSpan.FromMinutes(5); manager.MaxFailedAccessAttemptsBeforeLockout = 5; // Register two factor authentication providers. This application uses Phone and Emails as a step of receiving a code for verifying the user // You can write your own provider and plug in here. manager.RegisterTwoFactorProvider("PhoneCode", new PhoneNumberTokenProvider<ApplicationUser> { MessageFormat = "Your security code is: {0}" }); manager.RegisterTwoFactorProvider("EmailCode", new EmailTokenProvider<ApplicationUser> { Subject = "SecurityCode", BodyFormat = "Your security code is {0}" }); manager.EmailService = new EmailService(); manager.SmsService = new SmsService(); var dataProtectionProvider = options.DataProtectionProvider; if (dataProtectionProvider != null) { manager.UserTokenProvider = new DataProtectorTokenProvider<ApplicationUser>(dataProtectionProvider.Create("ASP.NET Identity")); } return manager; } } // Configure the RoleManager used in the application. RoleManager is defined in the ASP.NET Identity core assembly public class ApplicationRoleManager : RoleManager<IdentityRole> { public ApplicationRoleManager(IRoleStore<IdentityRole, string> roleStore) : base(roleStore) { } public static ApplicationRoleManager Create(IdentityFactoryOptions<ApplicationRoleManager> options, IOwinContext context) { return new ApplicationRoleManager(new RoleStore<IdentityRole>(context.Get<ApplicationDbContext>())); } } public class EmailService : IIdentityMessageService { public Task SendAsync(IdentityMessage message) { // Plug in your email service here to send an email. return Task.FromResult(0); } } public class SmsService : IIdentityMessageService { public Task SendAsync(IdentityMessage message) { // Plug in your sms service here to send a text message. return Task.FromResult(0); } } // This is useful if you do not want to tear down the database each time you run the application. // public class ApplicationDbInitializer : DropCreateDatabaseAlways<ApplicationDbContext> // This example shows you how to create a new database if the Model changes public class ApplicationDbInitializer : DropCreateDatabaseIfModelChanges<ApplicationDbContext> { protected override void Seed(ApplicationDbContext context) { InitializeIdentityForEF(context); base.Seed(context); } //Create User=[e-mail] with password=Admin@123456 in the Admin role public static void InitializeIdentityForEF(ApplicationDbContext db) { var userManager = HttpContext.Current.GetOwinContext().GetUserManager<ApplicationUserManager>(); var roleManager = HttpContext.Current.GetOwinContext().Get<ApplicationRoleManager>(); const string name = "[e-mail]"; const string password = "Admin@123456"; const string roleName = "Admin"; //Create Role Admin if it does not exist var role = roleManager.FindByName(roleName); if (role == null) { role = new IdentityRole(roleName); var roleresult = roleManager.Create(role); } var user = userManager.FindByName(name); if (user == null) { user = new ApplicationUser { UserName = name, Email = name }; var result = userManager.Create(user, password); result = userManager.SetLockoutEnabled(user.Id, false); } // Add user admin to Role Admin if not already added var rolesForUser = userManager.GetRoles(user.Id); if (!rolesForUser.Contains(role.Name)) { var result = userManager.AddToRole(user.Id, role.Name); } } } public class ApplicationSignInManager : SignInManager<ApplicationUser, string> { public ApplicationSignInManager(ApplicationUserManager userManager, IAuthenticationManager authenticationManager) : base(userManager, authenticationManager) { } public override Task<ClaimsIdentity> CreateUserIdentityAsync(ApplicationUser user) { return user.GenerateUserIdentityAsync((ApplicationUserManager)UserManager); } public static ApplicationSignInManager Create(IdentityFactoryOptions<ApplicationSignInManager> options, IOwinContext context) { return new ApplicationSignInManager(context.GetUserManager<ApplicationUserManager>(), context.Authentication); } } 

Thank!!

Here is what I did to make Unity play well with ASP.NET Identity 2.0:

I added the following to the RegisterTypes method in the UnityConfig class:

 container.RegisterType<DbContext, ApplicationDbContext>( new HierarchicalLifetimeManager()); container.RegisterType<UserManager<ApplicationUser>>( new HierarchicalLifetimeManager()); container.RegisterType<IUserStore<ApplicationUser>, UserStore<ApplicationUser>>( new HierarchicalLifetimeManager()); container.RegisterType<AccountController>( new InjectionConstructor()); 

Answer 2

Try adding the line below in the UnityConfig class:

 container.RegisterType<IAuthenticationManager>( new InjectionFactory( o => System.Web.HttpContext.Current.GetOwinContext().Authentication ) );

If you really want to use Unity to manage all your dependencies, you can also try registering IAuthenticationManager with Unity

  container.RegisterType<IAuthenticationManager>( new InjectionFactory(c => HttpContext.Current.GetOwinContext().Authentication)); 

With some minor changes, you can use Unity to resolve all the necessary dependencies for Identity Asp.net.

I found a great post on this (also verified by me) here:

This will also work as a complete configuration allowing you to use Unity with Identity 2.0:

 container.RegisterType<MyDbContext>(new PerRequestLifetimeManager(), new InjectionConstructor()); // Identity container.RegisterType<UserManager<User>>(new HierarchicalLifetimeManager()); container.RegisterType<SignInManager<User, string>>(new HierarchicalLifetimeManager()); container.RegisterType<IUserStore<User>, UserStore<User>>(new PerRequestLifetimeManager(), new InjectionFactory(x => new UserStore<User>(GetConfiguredContainer().Resolve<MyDbContext>()))); container.RegisterType<IAuthenticationManager>(new InjectionFactory(x => HttpContext.Current.GetOwinContext().Authentication)); 

With this parameter, you will not need to register the AccountController or ManageController types with Unity.

Reputation will not allow me to comment, but to add the marked user3849637s answer for MVC with Update 3 you will also need to add ManageController, as some functions use this with updated forests:

 container.RegisterType<ManageController>(new InjectionConstructor()); 

Answer 6

 container.RegisterFactory<IAuthenticationManager>(o => System.Web.HttpContext.Current.GetOwinContext().Authentication); 

This will answer the question posted by the OP, and will be a relevant answer for anyone who finds it through Google, like me. RegisterFactory is a new way to do this in Unity.
