The Entity type 'Personal' is part of a Hierarchy, but does not have a discriminator value configured

Question

I am trying to generate Migrations using the command:

dotnet ef migrations add InitialMigration --context MyContext 

and the same is returning me the following message.

System.Invalidoperationexception: The Entity type 'Personal' is part of a Hierarchy, but does not have a discriminator value configured.

In my classes I own PessoaFisica and PessoaJuridica inheriting from Pessoa and Funcionario inheriting from PessoaFisica (public class Funcionario : PessoaFisica).

modelBuilder.Entity<Funcionario>()
.ToTable("Funcionario");

Answer 1

What is happening, it seems to me, is that when using the TPH(Table Per Hierarchy) method you have to mention the value of the breakdown column. ex:

For that, in the Builder model, you have to do something like:

modelBuilder.Entity<Funcionario>()
    .Map<Funcionario>(m => m.Requires("Descriminator").HasValue("FUNC"))
