实体框架未建立关联并显示联结表

Question

We're trying to setup a new database and application using database first entity framework.

Everything is working well except for this bunch of tables. The entity framework isn't setup an association and is instead showing the junction tables in 2 of the 3 instances.

In the picture, ProfileIntegrationToolkit and ProfileProviderPrimary should disapear and should instead be associations.

Here's the code to reproduce the tables

/****** Object:  Table [dbo].[AuthorizedType]    Script Date: 25/02/2016 3:04:42 PM ******/

Am I doing something wrong? I've tried re-creating the constraints in SSMS but same result.

Edit 1- If i try reducing the amount of tables I import. I get similar issues.

Answer 1

That's a sneaky one! See this part of the DDL:

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

    FOREIGN KEY([ProfileId])

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

I indented the errant line. The foreign key to Provider should be off ProviderId , just as in ProfileProviderSecondary . The same error occurs in ProfileIntegrationToolKit .

Correct this, remove the junctions from the edmx, update the model from the database and you're ready to go.
