Entity framework core 在EF Core中生成具有所属实体的复合唯一约束/索引

我有一个实体拥有另一个实体

public class Entity1
{
  [Key]
  [DatabaseGenerated(DatabaseGeneratedOption.Identity)]
  public virtual int ID { get; set; }

  public string Property { get; set; }

  public Entity2 Description { get; set; }
}

public class Entity2
{
   public string Test { get; set; }
}

我需要在Entity1.Property和Entity2.Test上创建一个索引。配置如下

builder.OwnsOne(pt => pt.Description);

builder.HasIndex(p => new { p.Property, p.Description.Test }).IsUnique();
//builder.HasIndex("Property", "Description_Test").IsUnique();

我尝试了以上两种代码，但都不起作用。第一个说

The properties expression 'p => new <>f__AnonymousType3`7(Property = p.DeviceClassId, 
Test = p.Description.Test)' is not valid. The expression should represent a property 
access: 't => t.MyProperty'. When specifying multiple properties use an anonymous type:
't => new { t.MyProperty1, t.MyProperty2 }'.
Parameter name: propertyAccessExpression

这可以在不手动修改迁移的情况下实现吗？

显然EF Core还不支持此功能

请参阅GitHub上的此问题：

还有一个变通方法，我自己还没有测试过

The property 'Description_test' cannot be added to the type 'Entity1' because there was no 
property type specified and there is no corresponding CLR property or field. To add a 
shadow state property the property type must be specified.
