Question

假设我在下面的实体中定义了一个表公司：

public class Company
{
    public Guid CompanyId { get; set; }

    [Required]
    public string Name { get; set; }

    [MaxLength(50)]
    public string Uid { get; set; }

    ...
}

我需要另一张表CompanyHistory将公司的所有领域扩展到CompanyHistoryId，EffectiveDate，DEffectiveDate。我试过这样的话：

public class CompanyHistory : Company
{
    public Guid CompanyHistoryId { get; set; }

    public virtual Company { get; set; }
}

但是，而不是2个表，迁移会生成一个并组合所有列。

如果不按照此处的说明重新编写所有列，我如何获得相同的结果：

public class CompanyHistory
{
    public Guid CompanyHistoryId { get; set; }

    public Guid CompanyId { get; set; }
    public virtual Company Company { get; set; }

    [Required]
    public string Name { get; set; }

    [MaxLength(50)]
    public string Uid { get; set; }

    ...
}

EF Core代码首先是单独表的继承
