codefirst中的两个类

public partial class BaseEntity 
{
    public int ID { get; set; }
}

public partial class Fund : BaseEntity
{
   public int Name { get; set; }
}
public partial class InvestorFund : BaseEntity 
{
  public int FundID { get; set; }
}

映射类

this.Property(t => t.ID).HasColumnName("FundID");

我的代码首先加入SQL查询

from fund in context.Funds

join investorFund in context.InvestorFunds on fund.ID equals investorFund.FundID

抛出一个 Invalid column name Discriminator
