How to use interfaces like Dbset’s in the C#Entity Framework

Question

Hello, I’m making a solution where my entire business layer is in a separate project and in this project I created the layer relational structure from interfaces as shown in the example below:

// interfaces de definição de características 
public interface IHasIndex {
    int Id { get; set; }
}
...
// estrutura da aplicação
public interface IEmpresa: IHasIndex {
    string RazaoSocial { get; set; }
}
public interface IUsuario: IHasIndex {
    string Login { get; set; }
    string Senha { get; set; }
    IEmpresa Empresa { get; set; }
}
...

The intention is to take advantage of the multiple inheritance that the interfaces allow me and to standardize the nomenclature of the fields as well as to allow the use of the interfaces of defining characteristics as specific selectors, generalizing the application, reducing code, standardizing methods, etc...

My problem is time to generate the models of this solution. I am working with Entity Framework Core and even if it allows the use of interfaces in defining DbSet<T> (as shown at that link) I intend to use Model classes that implement the application logic interfaces, as shown below:

[Table("Empresa")]
public class EmpresaModel: IEmpresa {
    [Key]
    public int Id { get; set; }
    public string RazaoSocial { get; set; }
}
[Table("Usuario")]
public class UsuarioModel: IUsuario {
    [Key]
    public int Id { get; set; }
    public string Login { get; set; }
    public string Senha { get; set; }

    public int EmpresaId { get; set; } // FK para Empresa
    [ForeignKey("EmpresaId")]
    public EmpresaModel Empresa { get; set; }

}

When I set out to use EmpresaModel as the IEmpresa in class UsuarioModel, C# tells me that the interface has not been implemented. In my view, if EmpresaModel implements IEmpresa, then (theoretically) I could use the class instead of the interface. How to solve?

EDIT: To make the situation clearer based on what @Marconciliosouza said about multiple inheritance, I will expand the Iempresa interface with all the attributes and inheritances...

// interfaces de definição de características 
public interface IHasVisibility {
    bool Visivel { get; set; }
}
public interface IHasDefault {
    bool Padrao { get; set; }
}
public interface IHasCreationEvent {
    bool CriadoEm { get; set; }
}

// estrutura da aplicação
public interface IPessoaJuridica {
    string RazaoSocial { get; set; }
    string NomeFantasia { get; set; }
    string Cnpj { get; set; }
    string InscricaoEstadual { get; set; }
    string InscricaoMunicipal { get; set; }
}
public interface IPessoaFisica {
    string Nome { get; set; }
    string Sobrenome { get; set; }
    string Cpf { get; set; }
    string Rg { get; set; }
}
public interface IEndereco : IHasIndex {
    string Logradouro { get; set; }
    string Numero { get; set; }
    string Complemento { get; set; }
    string Bairro { get; set; }
    string Localidade { get; set; }
    string Uf { get; set; }
    string Pais { get; set; }
    string Cep { get; set; }
}
public interface IContato: IHasIndex {
    string Tipo { get; set; }
    string Descricao { get; set; }
    string Observacao { get; set; }
}
public interface IContatoWithDefault: IContato {
}
public interface IEmpresa : IHasIndex, IHasDefault, IHasCreationEvent, IHasVisibility {
    IPessoaJuridica PessoaJuridica { get; set; }
    IPessoaFisica PessoaFisica { get; set; }
    IEndereco Endereco { get; set;}
    ICollection<IContatoWithDefault> Contatos { get; set; }
}
