我一直在项目中使用 ADO.NET 实体数据模型来测试我一直在开发的安全/授权方法。我让一切都按我想要的方式工作，我需要在另一个生产项目中模仿这种行为。
另一个生产产品使用 Entity Framework Power Tools Beta 3 来生成类/实体和映射类。到目前为止，它只有模型和映射。
我有一个 Users 表、Roles 表和 UsersInRoles 表（等等）。
Roles 和 UsersInRoles 之间是一对多的关系，但 Users 和 UsersInRoles 之间是一对一的关系。
我认为我的数据库关系正确。ADO 模型似乎是这么认为的 :)
但是，当我在使用 Power Tools 生成的类时在我的 C# 代码中调用 db.Users 时，我得到：
{“执行命令定义时发生错误。有关详细信息，请参阅内部异常。”}
{"无效的列名 'Role_RoleId'。"}
当我执行 EF 命令 - 查看实体数据模型 DDL SQL 时，我看到一个名为 Role_RoleID 的列，这是不正确的......对吗？
数据库表 Users 中没有 Role_RoleId。此外，模型或映射文件中不会生成 UsersInRoles。我该如何解决？我很茫然。
