この度は、フィードバックをお送りいただき、誠にありがとうございます。現在、お送りいただきました報告内容に基づき問題を調査中ですので、しばらくお待ちください。よろしくお願いいたします。

[Problem Description]
When you delete an entity related to another one in the Entity Framework Designer window, build error 3013 occurs. No workaround for this build error is provided in Visual Studio 2008.

[Repro Steps]
1. Create an entity by selecting the Categories and Products tables for the Northwind database in the Entity Data Model wizard.
2. Select [Update Model from Database] in the edmx (Entity Designer) window and add the Suppliers table to the model.
3. Delete SupplierID from the Products entity.
4. Confirm there’s no build.
5. Delete the Suppliers entity.
6. When you build it, the following error occurs.
Error 2 Error 3013: Problem in Mapping Fragment starting at line 143, 155: Missing table mapping: Foreign key constraint 'K_Products_Suppliers' from table Products (SupplierID) to table Suppliers (SupplierID): no mapping specified for the table Suppliers.

7. Show the Model Browser.
8. Confirm FK_Products_Suppliers exists in the NorthwindMode.Store – constraint.
9. This seems to be the cause of the build error. FK_Products_Suppliers should be deleted from the Model Browser, but cannot.

[Actual Results]
I want to delete FK_Products_Suppliers from the Model Browser, but can never delete it and so resolve the build error.

[Expected Results]
A workaround for this issue should be provided (e.g., by showing the Delete option in the context menu of the Model Browser.)

Thanks for reporting this issue. We have made a change to this feature where you will get an option to delete the Store side information as well when you delete a C side Entity. This problem does not appear with the new feature in place.

問題をご報告いただきありがとうございます。私たちは、こちらの機能に変更を加えましたので、C-side のエンティティを削除する際に Store-side の情報も削除するオプションをご利用いただくことができるようになります。この新機能が備わったことにより、こちらの問題は発生しません。
