Question

我有一个带有此签名的名为Money的ValueObject：

public class Money : ValueObject
{
    public decimal Amount { get; private set; }
    public Currency Currency { get; private set; }

    private Money(decimal amount, Currency currency = Currency.Nigerian_Naira)
    {
        Guard.Against.Zero(amount, nameof(amount));
        Amount = amount;
        Currency = currency;
    }

    private Money(){}

    public static Money Create(decimal amount, Currency currency = Currency.Nigerian_Naira)
    {
        return new Money(amount, currency);
    }

    public bool IsEmpty()
    {
        return Amount == 0m && Currency == Currency.Nigerian_Naira;
    }
    protected override IEnumerable<object> GetAtomicValues()
    {
        yield return Amount;
        yield return Currency;
    }
}

并且我有一个拥有此值对象的实体，如下所示：

public class Account : BaseEntity
{

    public Account()
    {
        AccountId = Guid.NewGuid();
    }

    public Guid AccountId { get; set; }

    [Required]
    [StringLength(25)]
    public string AccountName { get; set; }

    [Required]
    public Money AccountBalance { get; set; }

    [Required]
    public bool IsActivated { get; set; }

    public List<Entity2> Entity2 { get; set; }

    public List<Entity1> Entity1 { get; set; }

}

我已经在Context中配置了所有权，如下所示：

modelBuilder.Entity<Account>()
                    .OwnsOne(c => c.AccountBalance);

这是我的基本实体，基本上带有如下所示的简单属性：

public abstract class BaseEntity
{
    public bool IsDeleted { get; set; }

    public DateTimeOffset CreatedDate { get; set; }

    public DateTimeOffset UpdatedDate { get; set; }

}

现在，如果我想在单元测试中将更改保存到内存数据库中，则会出现错误提示：

Error Message:
System.InvalidOperationException : The property 'UpdatedDate' on entity type 
'CashAccount.AccountBalance#Money' could not be found. Ensure that the 
property exists and has been included in the model.

updatedDate属性来自所有实体都继承自的基本实体类型。我一直在梳理efcore文档，但没有发现任何有关这种怪异行为的线索。

我基本上是想将Account保存到数据库中，这给了我这个错误，说Money没有属性UpdatedDate，该属性应该属于实体。 EF6复杂类型从来都不是问题。

EfCore 2.2拥有的类型选择实体基础属性
