代码

代码相当广泛。这些是最后更改的类。

public class Entidade : EntityNome, IAuditavel
{
    public DateTime CriadoAs { get; set; }
    public virtual Usuario CriadoPor { get; set; }
    public DateTime? AtualizadoAs { get; set; }
    public virtual Usuario AtualizadoPor { get; set; }
}

public class Empresa : Entidade
{
    public string RazaoSocial { get; set; }
    public string CNPJ { get; set; }
    public string InscricaoEstadual { get; set; }
    public string WebSite { get; set; } 

    public virtual ICollection<Pessoa> Representantes { get; set; }
    public virtual Pessoa Contato { get; set; }

    public virtual ICollection<Telefone> Telefones { get; set; }
    public virtual ICollection<Endereco> Enderecos { get; set; }
    public virtual ICollection<Email> Emails { get; set; }
}   

public class Agencia : Empresa
{
    public string Identificacao { get; set; }
    public virtual Regional Regional { get; set; }
    public virtual ICollection<Pessoa> Gerentes { get; set; }
}   

public class Regional : EntityNome
{
    public virtual ICollection<Pessoa> Contatos { get; set; }
}

配置

public class EntidadeConfiguracao : EntityTypeConfiguration<Entidade>
{
    public EntidadeConfiguracao()
    {
        Property(p => p.Nome).IsName(true);
        HasRequired(p => p.CriadoPor).WithMany().WillCascadeOnDelete(false);

        ToTable("Entidades");
    }
}

public class EmpresaConfiguracao : EntityTypeConfiguration<Empresa>
{
    public EmpresaConfiguracao()
    {
        HasMany(p => p.Telefones).WithMany().Map(m => m.ToTable("EmpresaTelefones"));
        HasMany(p => p.Emails).WithMany().Map(m => m.ToTable("EmpresaEmails"));
        HasMany(p => p.Enderecos).WithMany().Map(m => m.ToTable("EmpresaEnderecos"));
        HasMany(p => p.Representantes).WithMany().Map(m => m.ToTable("EmpresaRepresentantes"));

        ToTable("Empresas");
    }
}

public class AgenciaConfiguracao : EntityTypeConfiguration<Agencia>
{
    public AgenciaConfiguracao()
    {
        HasRequired(p => p.Regional).WithMany().WillCascadeOnDelete(true); //.HasForeignKey(p => p.RegionalId)
        Property(p => p.Identificacao).IsRequired().HasMaxLength(10);
        HasMany(p => p.Gerentes).WithMany().Map(m => m.ToTable("AgenciaGerentes"));

        ToTable("Agencias");
    }
}

public class RegionalConfiguracao : EntityTypeConfiguration<Regional>
{
    public RegionalConfiguracao()
    {
        Property(p => p.Nome).IsName(true);
        HasMany(p => p.Contatos).WithMany().Map(m => m.ToTable("RegionalContatos"));

        ToTable("Regionais");
    }
}

    【解决方案1】:

    您需要重新创建迁移。看看EF6 Beta1 announcement中的“你需要知道的事情”部分

    这是 EF codeplex 网站上的相关work item
