How can i use UserManager with custom user? - asp.net-core

Question

I have created custom user class which inherits IdentityUser<int>.
[Table("Users", Schema = "UserData")]
public class User : IdentityUser<int>
{
/// <summary>
/// Property for sake of creating One-to-One relationship UserDetails -> User
/// </summary>
[Required]
public UserDetails UserDetails { get; set; }
}
public class BlogDbContext : IdentityDbContext<User, IdentityRole<int>, int>
{
public BlogDbContext(DbContextOptions<BlogDbContext> options)
: base(options) {}
protected override void OnModelCreating(ModelBuilder builder)
{
builder.ApplyConfigurationsFromAssembly(Assembly.GetExecutingAssembly());
//UserDataConfig
builder.ApplyConfiguration(new UserConfiguration());
builder.ApplyConfiguration(new UserDetailsConfiguration());
//UserData
builder.Entity<Location>()
.HasOne<UserDetails>(s => s.UserDetails)
.WithOne(g => g.Location)
.HasForeignKey<UserDetails>(ad => ad.LocationId);
builder.Entity<User>()
.HasOne<UserDetails>(s => s.UserDetails)
.WithOne(g => g.User)
.HasForeignKey<UserDetails>(ad => ad.UserId);
base.OnModelCreating(builder);
}
//UserData
public DbSet<User> Users { get; set; }
public DbSet<UserDetails> UserDetails { get; set; }
}
}
Now I am trying to create following field
private UserManager<User, int> _userManager;
And my error:
The type 'ApplicationCore.DataModel.UserData.User' cannot be used as
type parameter 'TUser' in the generic type or method
'UserManager<TUser, TKey>
How can I fix it? Thanks for your attention.

Answer 1

Replace User to IdentityUser and Role to IdentityRole and working fine. like
public class DataContext : IdentityDbContext<IdentityUser,IdentityRole, string, IdentityUserClaim<string>, IdentityUserRole<string>,
IdentityUserLogin<string>, IdentityRoleClaim<string>,IdentityUserToken<string>>
Or use:-
public class ApplicationUser : IdentityUser<int>
{
}
public class ApplicationRole : IdentityRole<int>
{
}
public class BlogDbContext : IdentityDbContext<ApplicationUser, ApplicationRole, int>
{
}
It will resolve your issue.
