value-objects - EFCore3.1中如何映射ValueObject

Question

实体：

public class Good : FullAuditedAggregateRoot<Guid>
{
   ///******///
  public virtual SaleStates SaleStates { get; set; }
}

模型构建器：

builder.Entity<Good>(b =>
{
  ///******///
  b.OwnsOne(f=>f.SaleStates).WithOwner();
}

错误：

System.InvalidOperationException : The type 'SaleStates' cannot be marked as owned because a non-owned entity type with the same name already exists.

这似乎是ABP中的一个问题。遇到这个问题时，唯一对我有帮助的是[Owned]在值对象的类名上方使用属性。
