基于实体框架的脚手架模型 - 验证错误

Question

我的应用程序配置为使用SQLRoleManager。我只是创建了数据库，配置了web.config，让应用程序创建并填充数据库表。

我想要一个管理视图来执行一些简单的操作，例如添加和删除用户。因此，我使用脚手架向导创建了一个实体框架数据上下文，并指示它仅围绕表构建。 （没有检查视图和存储过程）。

我希望接下来要做的是然后将控制器搭建并查看并最终获得此数据的模型。当我右键单击控制器时，我选择使用实体框架添加带有视图的控制器。我填写适当的信息，为模型选择一个空类。

我收到以下错误，表示数据缺少密钥，但它们实际上是在数据库和实体模型中定义的。关于我在哪里出错的任何想法？我需要预先建立模型吗？我希望有视觉工作室自动创建这些。

修改

同样，这些表都有主键和外键。我可以从Sql Management Studio以及.edmx图中确认这一点。波纹管代码是自动生成的。我需要添加密钥吗？
