Customize Identityuserclaim

Question

I’m trying to customize the Identity Claims table, through the Identityuserclaim class.

I am using a mapping, through the Entitytypeconfiguration class, but I get the error:

A Configuration for type 'Microsoft.AspNet.Identity.EntityFramework.Identityuserclaim' has already been Added. To Reference the existing Configuration use the Entity() or Complextype() methods.

The Dbcontext Onmodelcreating method looks like this:

protected override void OnModelCreating(DbModelBuilder modelBuilder)
{
    base.OnModelCreating(modelBuilder);

    modelBuilder.Configurations.Add(new ApplicationUserClaimConfiguration());
    modelBuilder.Configurations.Add(new ApplicationIdentityUserClaimConfiguration());

    modelBuilder.Configurations.Add(new ApplicationIdentityRoleConfiguration());
    modelBuilder.Configurations.Add(new ApplicationRoleConfiguration());

    modelBuilder.Configurations.Add(new ApplicationUserConfiguration());
}

The Applicationidentityuserclaimconfiguration class looks like this:

public class ApplicationIdentityUserClaimConfiguration : EntityTypeConfiguration<IdentityUserClaim>
{
    public ApplicationIdentityUserClaimConfiguration()
    {
        ToTable("UserClaim");
    }
}

The class Applicationuserclaimconfiguration maps the class Applicationuserclaim : Identityuserclaim to the same table Userclaim.

Does anyone know how to solve this problem?

Thank you.

Here’s an example mapping can do separate the way you did more this mode also works.

protected override void OnModelCreating(DbModelBuilder modelBuilder)
 {
 base.OnModelCreating(modelBuilder);
 //sobrescrever a entidade IdentityUser pela entidade Usuario
 modelBuilder.Entity<Usuario>().ToTable("Usuarios")
 .Property(u => u.Id).HasColumnName("IdUsuario");
 modelBuilder.Entity<IdentityRole>().ToTable("Perfis");
 modelBuilder.Entity<IdentityUserRole>().ToTable("UsuariosPerfis");
 modelBuilder.Entity<IdentityUserLogin>().ToTable("UsuariosLogin");
 modelBuilder.Entity<IdentityUserClaim>().ToTable("UsuariosClaims");
 }
