自动创建数据库和表之后，使用事务插入多张表出错 Object does not match target type. 返回

自动创建数据库和两张表 t_product 和 t_product_model

模型如下：

startup.cs 中写入自动创建数据库和表的方法

进入建表的方法

自动建库建表完成，好使，没出问题，而且修改表和字段，字段的增删都好使。

创建简单的仓储

ProductRepostory 产品仓储 继承仓储基类，两个简单的方法

ProductModelRepostory 仓储继承了 仓储基类 一个简单的添加方法

执行添加功能是要往两张表添加数据

由于程序出错，没有做事务的提交和回滚，数据库表中都没有数据。

自己经过多种测试，不是DB问题，只要不执行自动创建数据库和表，执行添加就不会出错，感觉是最后一张表没有放到映射集合中，导致添加表数据就找不到映射类。大神们来帮帮忙。
