在输出程序集中指定.csdl / .ssdl / .msl元数据文件的位置 [英] Specifying location of .csdl / .ssdl / .msl Metadata files within the output assembly

问题描述

我有一个包含我已经成功使用的数据模型的EF项目。 元数据人工处理选项设置为嵌入输出装配。

由于.edmx文件位于项目的根文件夹中，因此使用的元数据字符串EntityConnectionStringBuilder设置为：

res：//*/myProject.csdl | res：//*/myProject.ssdl | res：/ / * / myProject.msl

当我重组项目时，我将.ecdm文件移动到子文件夹：
/ DataLayer / myProject / ，我将元数据字符串更改为：

res：// * / DataLayer / myProject / myProject.csdl | res：//*/DataLayer/myProject/myProject.ssdl | res：//*/DataLayer/myProject/myProject.msl

现在会导致错误（指定的元数据路径无效），但我看不到元数据中指定的文件夹路径有什么问题。

我知道我可以将.ecdm文件移回根目录，但我以前遇到过这个问题，无法解决它 - 有什么明显的'm missing？

解决方案

我终于明白了。

文件夹应该与'。'不分开'/'。

元数据的正确格式是：

  RES：//*/DataLayer.myProject.myProject.csdl | RES：//*/DataLayer.myProject.myProject.ssdl | RES：//*/DataLayer.myProject.myProject .msl 
  

希望这样可以让某人从头撞到墙上一段时间！

I have an EF project that containing my data model that I have been successfully using. The "Metadata Artifact Processing" option is set to "Embed in Output Assembly".

As the .edmx file was in the root folder of the project the metadata string used in the EntityConnectionStringBuilder was set to:

res://*/myProject.csdl|res://*/myProject.ssdl|res://*/myProject.msl

When I was restructuring the project, I moved the .ecdm file into a subfolder: /DataLayer/myProject/ and I changed the metadata string to:

res://*/DataLayer/myProject/myProject.csdl|res://*/DataLayer/myProject/myProject.ssdl|res://*/DataLayer/myProject/myProject.msl

This now causes an error ("The specified metadata path is not valid") but I can't see what's wrong with the folder path I've specified in the metadata.

I know that I can just move the .ecdm file back to the root but I've had this problem before and couldn't fix it - is there something obvious I'm missing?

解决方案

I finally worked it out.

The folders should be separated with '.' not '/'.

The correct format for the metadata is:

res://*/DataLayer.myProject.myProject.csdl|res://*/DataLayer.myProject.myProject.ssdl|res://*/DataLayer.myProject.myProject.msl

Hopefully this will save someone from banging their head against the wall for a while!
