Question

我们正在尝试使用数据库第一实体框架设置新的数据库和应用程序。

除了这一堆表之外，一切都运行良好。实体框架未设置关联，而是在3个实例中的2个中显示联结表。

在图片中，ProfileIntegrationToolkit和ProfileProviderPrimary应该消失，而应该是关联。

这是重现表格的代码

我做错了吗？我尝试在SSMS中重新创建约束但结果相同。

编辑1- 如果我尝试减少我导入的表的数量。我遇到了类似的问题。

那是一个偷偷摸摸的人！请参阅DDL的这一部分：

ALTER TABLE [dbo].[ProfileProviderPrimary]  WITH CHECK
ADD  CONSTRAINT [FK_ProfileProviderPrimary_Provider]

    FOREIGN KEY([ProfileId])

REFERENCES [dbo].[Provider] ([Id])

我缩进了错误的行。 Provider的外键应该关闭ProviderId，就像在ProfileProviderSecondary中一样。 ProfileIntegrationToolKit中出现同样的错误。

更正此问题，从edmx中删除联结，从数据库更新模型，然后就可以开始了。

实体框架没有建立关联并显示联结表
