代码首先TPT继承中的多对多关系抛出3034异常

Question

加载包含多对多关系的实体时出错。 两个实体都从“TPT”基础实体继承 异常是（223,10）：错误3034：从第223,229行开始映射片段时出现问题：具有不同键的两个实体映射到同一行。确保这两个映射片段不会将具有不同键的两组实体映射到同一组行。

（229,10）：错误3034：从第229,410行开始映射片段时出现问题：具有不同键的两个实体映射到同一行。确保这两个映射片段不会将具有不同键的两组实体映射到同一组行。

映射是：

 public DomainMapping()
    {

        ToTable("Domain");

        Property(d => d.FooterText).IsOptional();
        Property(d => d.ExpiryDate).IsOptional();
        Property(d => d.KeyWord).IsOptional();
        Property(d => d.DefaultLanguage).IsRequired();
        Property(d => d.TimezoneOffset).IsRequired();
        Property(d => d.RootFolder).IsRequired();
        Property(d => d.DefaultSkin).IsRequired();
        Property(d => d.Path).IsRequired();

        HasRequired(d => d.Administrator).WithMany().HasForeignKey(d => d.AdministratorId);
        HasRequired(d => d.AdministratorRole).WithMany().HasForeignKey(d => d.AdministratorRoleId);



        HasOptional(t => t.Parent).WithMany(d => d.Children).HasForeignKey(d => d.ParentId);


    }

和

 public ModuleDefinitionMapping()
    {
        ToTable("ModuleDefinition");

        Property(d => d.ModuleVersion).
        IsRequired().
        HasMaxLength(16);

        Property(d => d.Assembly).
        IsRequired().
        HasMaxLength(256);


        HasRequired(d => d.DesktopControl).WithMany().HasForeignKey(d=>d.DesktopControlId);
        HasRequired(d => d.SettingControl).WithMany().HasForeignKey(d=>d.SettingControlId);
        HasMany(d => d.Domains).WithMany(t => t.ModuleDefinitions).Map(p => { 
        p.ToTable("DomainModuleDefinition");
        p.MapRightKey("DomainId");
        p.MapLeftKey("ModuldeDefinitionId");
        });
    }

，实体是：

 public class ModuleDefinition :SystemEntity
{
    #region Primitive Properties


    public virtual string ModuleVersion
    {
        get;
        set;
    }

请帮助我。我已经研究并花了很多时间，但没有机会解决它
