升级从3.5至4时，在EDMX文件警告 [英] Warnings in edmx file when upgrading from 3.5 to 4

问题描述

我更新了我的解决方案，从.NET 3.5至4.0，并感谢上帝，我不得不解决小事情。 但我不明白的是，在EDMX文件生成很多的警告是这样的：

I updated my solution from .NET 3.5 to 4.0, and thanks god, I just had to fix minor things. But what I don't understand is, the edmx file generated many warnings like this:

Error 2005: Mapping Association 'FK_CP_C' is redundant:
Its referential integrity constraint provides sufficient information.
You can safely delete the mapping information for this association.

你有没有遇到过这种问题
我应该做的冒险和删除这些关联？
我试图谷歌，但没能发现任何东西。

Have you ever encountered this?
Should I do take the risk and delete the associations?
I tried to google it but wasn't able to find anything.

感谢

推荐答案

嗯仅供参考我之前所做的项目的备份，删除了这些thoat报告了一个错误，更新了模型关联，并警告都没有了。

Well FYI I made a backup of the project before, removed those associations thoat reported an error, updated the model, and the warnings are gone.

我错过了发现什么样的联想造成了警告。

I missed to notice what kind of associations caused the warnings.

希望这可以帮助别人的未来。

Hope this might help someone in the future.
