What package contains implementation for IUserEmailStore

Question

I am working on the project that implements two factor authentication using SMS in C#. I am trying to use the interface called IUserEmailStore in my controller - so my controller's constructor look like this:

public AccountsController(
    SignInManager<User> signInManager,
    UserManager<User> userManager,
    IUserStore<User> userStore,
    IUserEmailStore<User> emailStore,
    RepositoryContext context,
    IMapper mapper, 
    UrlEncoder urlEncoder,
    JwtHandler jwtHandler)
    {
        _signInManager = signInManager;
        _userStore = userStore;
        _userManager = userManager;
        _emailStore = emailStore;
        _mapper = mapper;
        _urlEncoder = urlEncoder;
        _jwtHandler = jwtHandler;
        _context = context;
    }

I am getting the following exception:

System.InvalidOperationException: Unable to resolve service for type 'Microsoft.AspNetCore.Identity.IUserEmailStore`1[TwoFactorAuthenticationGoogleAuthenticatorAngular.Models.User]' while attempting to activate 'TwoFactorAuthenticationGoogleAuthenticatorAngular.Controllers.AccountsController'. 
    at Microsoft.Extensions.DependencyInjection.ActivatorUtilities.GetService(IServiceProvider sp, Type type, Type requiredBy, Boolean isDefaultParameterRequired)

--- End of stack trace from previous location ---
         

I included the following relevant packages - including Microsoft.Extensions.Identity.Core referred by the Microsoft documentation of the IUserEmailStore<TUser> interface.

I am running out of ideas. Can somebody help?

I have solved the problem by finding how other projects tackled it. So basically I don't DI the IUserEmailStore into my controller. I DI instead a IUserStore and I cast it to IUserEmailStore - as Microsoft returns really IUserEmailStore (IUserEmailStore derives from IUserStore). That's it. Hope it helps someone.
