Breezejs保存实体继承问题

Question

我正在为我的SPA使用breezejs和membershipreboot，我试图覆盖beforesaveentitiesdelegate以添加新客户。

我有一个客户类，它继承自membershipreboot'RelationalUserAccount'，如下所示：

public class Customer : RelationalUserAccount
{
    public virtual string FirstName { get; private set; }
    public virtual string LastName { get; private set; }
}

我将以下代码用于'BeforeSaveEntitiesDelegate'：

public Dictionary<Type, List<EntityInfo>> AddCustomer(Dictionary<Type, List<EntityInfo>> saveMap)
        {
                Dictionary<Type, List<EntityInfo>> newSaveMap = new Dictionary<Type, List<EntityInfo>>();

                var type = saveMap.FirstOrDefault();

                if (type.Key == typeof(Customer))
                {
                    EntityInfo entityInfo = type.Value.First();

                    List<EntityInfo> customers = new List<EntityInfo>();

                    if (entityInfo.EntityState == EntityState.Added)
                    {
                        Customer customertoCreate = entityInfo.Entity as Customer;}

                        newSaveMap.Add(typeof(Customer), customers);
                    }
                }
            }
            return newSaveMap;
        }

当我进入代码时，只填充了firstname和lastname字段，其他任何继承的字段都没有包含任何数据，'customer'实体的基本类型似乎是'customer' - 不应该是RelationalUserAccount

奇怪的是，在下面的代码中，savebundle似乎有正确的数据：

    public SaveResult CustomerAdd(JObject saveBundle)
    {
        CustomerBusinessLogic customerLogic = new CustomerBusinessLogic(mContextProvider);
        mContextProvider.BeforeSaveEntitiesDelegate = customerLogic.AddCustomer;
        return mContextProvider.SaveChanges(saveBundle);
    }

这是saveBundle的转储，因为您可以看到填充了用户名和电子邮件字段：

    {
      "Key": -1,
      "FirstName": "asdf",
