ASP.NET Core - custom implementation of AspNetCore.Identity not working

Question

I am creating a fully custom implementation of AspNetCore.Identity because I want it to TKeybe System.Guidacross the board. Regards, I have received types for ...

• Role : IdentityRole<Guid, UserRole, RoleClaim>
• RoleClaim : IdentityRoleClaim<Guid>
• User : IdentityUser<Guid, UserClaim, UserRole, UserLogin>
• UserClaim : IdentityUserClaim<Guid>
• UserLogin : IdentityUserLogin<Guid>
• UserRole : IdentityUserRole<Guid>
• UserToken : IdentityUserToken<Guid>
  
  
• ApplicationDbContext : IdentityDbContext<User, Role, Guid, UserClaim, UserRole, UserLogin, RoleClaim, UserToken>
  
  
• ApplicationRoleManager : RoleManager<Role>
• ApplicationRoleStore : RoleStore<Role, ApplicationDbContext, Guid, UserRole, RoleClaim>
• ApplicationSignInManager : SignInManager<User>
• ApplicationUserManager : UserManager<User>
• **ApplicationUserStore** : UserStore<User, Role, ApplicationDbContext, Guid, UserClaim, UserRole, UserLogin, UserToken>

ApplicationUserStore is a child issue!

Implementation

namespace NewCo.Identity
{
    using Microsoft.AspNetCore.Identity.EntityFrameworkCore;
    using System;

    public sealed class Role : IdentityRole<Guid, UserRole, RoleClaim>
    {
    }
}

namespace NewCo.Identity
{
    using Microsoft.AspNetCore.Identity.EntityFrameworkCore;
    using System;

    public sealed class UserRole : IdentityUserRole<Guid>
    {
    }
}

namespace NewCo.Identity
{
    using Microsoft.AspNetCore.Identity.EntityFrameworkCore;
    using System;

    public sealed class RoleClaim : IdentityRoleClaim<Guid>
    {
    }
}

// The problem is here...

namespace NewCo.Identity
{
    using Microsoft.AspNetCore.Identity;
    using Microsoft.AspNetCore.Identity.EntityFrameworkCore;
    using System;
    using System.Security.Claims;

    public sealed class ApplicationUserStore : UserStore<User, Role, ApplicationDbContext, Guid, UserClaim, UserRole, UserLogin, UserToken>
    {
    }
}

Error

The type 'NewCo.Identity.Role' cannot be used as a parameter of the type 'TRole' in the generic type or method 'UserStore'. There is no implicit link conversion from 'NewCo.Identity.Role' to 'Microsoft.AspNetCore.Identity.EntityFrameworkCore.IdentityRole>.

As far as I can tell, if this is not a problem (co / contra / in), all the code checks ... that I was wrong?

ApplicationUserStore RoleClaim ( NuGet, ):

    ApplicationUserStore : UserStore<
            User, Role, ApplicationDbContext, 
            Guid, UserClaim, UserRole, 
            UserLogin, UserToken, RoleClaim>

, ApplicationRoleStore , RoleClaim,

protected override RoleClaim CreateRoleClaim(Role role, Claim claim)
{
    return new RoleClaim
    {
        RoleId = role.Id,
        ClaimType = claim.Type,
        ClaimValue = claim.Value
    };
}

ApplicationUserStore :

protected override UserClaim CreateUserClaim(User user, Claim claim)
{
    var userClaim = new UserClaim { UserId = user.Id };
    userClaim.InitializeFromClaim(claim);
    return userClaim;
}

protected override UserLogin CreateUserLogin(User user, UserLoginInfo login)
{
    return new UserLogin
    {
        UserId = user.Id,
        ProviderKey = login.ProviderKey,
        LoginProvider = login.LoginProvider,
        ProviderDisplayName = login.ProviderDisplayName
    };
}

protected override UserRole CreateUserRole(User user, Role role)
{
    return new UserRole
    {
        UserId = user.Id,
        RoleId = role.Id
    };
}

protected override UserToken CreateUserToken(User user, string loginProvider, string name, string value)
{
    return new UserToken
    {
        UserId = user.Id,
        LoginProvider = loginProvider,
        Name = name,
        Value = value
    };
}

              .AddDefaultTokenProviders();
