C# 实体框架下基于TPT设计的多级继承

我想在EF中实现以下模型作为TPT设计

我的代码如下：

基本型号

public abstract class Product
{
    public int Id { get; set; }
    public DateTime ProductionDate { get; set; }
}

public abstract class Product
{
    public int Id { get; set; }
    public DateTime ProductionDate { get; set; }
}

车型

public abstract class Car : Product
{
    public string ChassisNumber { get; set; }
    public string DriverName { get; set; }
}

[Table("TeslaCars")]
public class TeslaCar : Car
{
    public string Battery { get; set; }
    public int Temperature { get; set; }
}

[Table("PorscheCars")]
public class PorscheCar : Car
{
    public int FuelTank { get; set; }
}

public abstract class Motorcycle : Product
{
    public string RiderName { get; set; }
    public bool IsRacing { get; set; }
}

[Table("CrossMotorcycles")]
public class CrossMotorcycle : Motorcycle
{
    public int MaximumJump { get; set; }
}

[Table("KipsMotorcycles")]
public class KipsMotorcycle : Motorcycle
{
    public long MaximumSpeed { get; set; }
}

[Table("Cars")]
public abstract class Car : Product
{
    public string ChassisNumber { get; set; }
    public string DriverName { get; set; }
}

[Table("TeslaCars")]
public class TeslaCar : Car
{
    public string Battery { get; set; }
    public int Temperature { get; set; }
}

[Table("PorscheCars")]
public class PorscheCar : Car
{
    public int FuelTank { get; set; }
}

[Table("Motorcycles")]
public abstract class Motorcycle : Product
{
    public string RiderName { get; set; }
    public bool IsRacing { get; set; }
}

[Table("CrossMotorcycles")]
public class CrossMotorcycle : Motorcycle
{
    public int MaximumJump { get; set; }
}

[Table("KipsMotorcycles")]
public class KipsMotorcycle : Motorcycle
{
    public long MaximumSpeed { get; set; }
}

摩托车型号

public abstract class Car : Product
{
    public string ChassisNumber { get; set; }
    public string DriverName { get; set; }
}

[Table("TeslaCars")]
public class TeslaCar : Car
{
    public string Battery { get; set; }
    public int Temperature { get; set; }
}

[Table("PorscheCars")]
public class PorscheCar : Car
{
    public int FuelTank { get; set; }
}

public abstract class Motorcycle : Product
{
    public string RiderName { get; set; }
    public bool IsRacing { get; set; }
}

[Table("CrossMotorcycles")]
public class CrossMotorcycle : Motorcycle
{
    public int MaximumJump { get; set; }
}

[Table("KipsMotorcycles")]
public class KipsMotorcycle : Motorcycle
{
    public long MaximumSpeed { get; set; }
}

[Table("Cars")]
public abstract class Car : Product
{
    public string ChassisNumber { get; set; }
    public string DriverName { get; set; }
}

[Table("TeslaCars")]
public class TeslaCar : Car
{
    public string Battery { get; set; }
    public int Temperature { get; set; }
}

[Table("PorscheCars")]
public class PorscheCar : Car
{
    public int FuelTank { get; set; }
}

[Table("Motorcycles")]
public abstract class Motorcycle : Product
{
    public string RiderName { get; set; }
    public bool IsRacing { get; set; }
}

[Table("CrossMotorcycles")]
public class CrossMotorcycle : Motorcycle
{
    public int MaximumJump { get; set; }
}

[Table("KipsMotorcycles")]
public class KipsMotorcycle : Motorcycle
{
    public long MaximumSpeed { get; set; }
}

但问题是，在创建表之后，只有TPT设计的最后一步，TPH设计之上的层被创建

我的代码输出如下表所示：

我应该如何修改代码以在所有级别的表中遵循TPT设计？ 在最终输出中，我需要制作以下表格：

我终于得到了答案

在这种情况下，我需要在单独的表中设置汽车型号和摩托车型号的唯一字段，但是上面的代码默认使用TPH设计

因此，我们必须以这种方式更改代码：

基本型号

public abstract class Product
{
    public int Id { get; set; }
    public DateTime ProductionDate { get; set; }
}

public abstract class Product
{
    public int Id { get; set; }
    public DateTime ProductionDate { get; set; }
}

车型

public abstract class Car : Product
{
    public string ChassisNumber { get; set; }
    public string DriverName { get; set; }
}

[Table("TeslaCars")]
public class TeslaCar : Car
{
    public string Battery { get; set; }
    public int Temperature { get; set; }
}

[Table("PorscheCars")]
public class PorscheCar : Car
{
    public int FuelTank { get; set; }
}

public abstract class Motorcycle : Product
{
    public string RiderName { get; set; }
    public bool IsRacing { get; set; }
}

[Table("CrossMotorcycles")]
public class CrossMotorcycle : Motorcycle
{
    public int MaximumJump { get; set; }
}

[Table("KipsMotorcycles")]
public class KipsMotorcycle : Motorcycle
{
    public long MaximumSpeed { get; set; }

如果您使用的是EF Core，我相信它仍然只支持TPH。EF6支持TPH和TPT。我的项目是ASP.NETMVC5，我使用的是EF（不是EF核心）。在EF支持两者的同时，实现TPT设计也是我的目标。
