实体框架元数据异常-dll资源中没有csdl，ssdl，msl [英] Entity framework metadata exception - No csdl, ssdl, msl in dll resources

问题描述

我有DAL(模型第一个实体框架4.1)和在单独项目中使用它的Service.一切工作正常，但是在进行一些较小的更改(例如我从数据库生成模型)后，它停止了工作.我现在收到元数据异常. 经过许多小时的研究，我下载了ILSpy并检查DAL.dll中是否没有资源. 我的连接字符串如下:

I have DAL (model first entity framework 4.1) and Service which is using it in separate projects. Everything was working fine, but after some minor changes (for example I generated model from database) it stoppedd working. I am now getting metadata exception. After many hours of research I downloaded ILSpy and checked that inside DAL.dll there are no resources. My connection string looks like:

metadata=res://*/DataModel.TerminalRegistryModel.csdl|
         res://*/DataModel.TerminalRegistryModel.ssdl|
         res://*/DataModel.TerminalRegistryModel.msl;

EDMX文件元数据工件处理中的ANd设置为Embed in Output Assembly. 什么会导致我的问题?

ANd in EDMX file metadata artifact processing is set to Embed in Output Assembly. What can cause my problem?

推荐答案

标准元数据字符串如下所示:
metadata=res://*/Model.csdl|res://*/Model.ssdl|res://*/Model.msl
在大多数情况下，这都可以正常工作.但是，在某些Entity Framework中会感到困惑，并且不知道要查找哪个dll.因此，请将元数据字符串更改为:
metadata=res://nameOfDll/Model.csdl|res://nameOfDll/Model.ssdl|res://nameOfDll/Model.msl

The standard metadata string looks like this:
metadata=res://*/Model.csdl|res://*/Model.ssdl|res://*/Model.msl
And this works fine in most cases. However, in some Entity Framework get confused and does not know which dll to look in. Therefore, change the metadata string to:
metadata=res://nameOfDll/Model.csdl|res://nameOfDll/Model.ssdl|res://nameOfDll/Model.msl
