我意识到这个问题在此之前已经被问过并解决了很多次，并且有很多有用的帖子，比如这个...... http://blogs.teamb.com/craigstuntz/2010/08/13/38628/ 但不幸的是没有任何建议对我有用，所以我发帖是希望有人能发现我没见过的东西。
我有一个数据库项目 Sp_CodeGenerator - 我已连接到数据库。我的连接字符串是
<add name="AdWorksLTEntities" connectionString="metadata=res://*/Sp_CodeGenerator.Model1.csdl|res://*/Sp_CodeGenerator.Model1.ssdl|res://*/Sp_CodeGenerator.Model1.msl;provider=System.Data.SqlClient;provider connection string="Data Source=EIRCOM;Initial Catalog=AdventureWorksLT2008R2;Integrated Security=True;MultipleActiveResultSets=True;Application Name=EntityFramework"" providerName="System.Data.EntityClient"/>
我试过//*/Sp_CodeGenerator.Model...用 dll//Sp_CodeGenerator/Sp_CodeGenerator.Model.csdl等的名称替换，但它不起作用。
我还删除了 .config 文件中的所有引用，删除了 .edmx 文件和实体框架生成的模板文件并多次启动，但它不起作用。
我可以在我的目录结构中看到 edmx 文件：Model1.csdl、Model1.msl、Model1.ssdl 位于名为 edmxResourcesToEmbed 的文件夹中，它们可以在 C:\Sp_CodeGenerator\Sp_CodeGenerator\obj\x86 中找到
所以完整路径是 C:\Sp_CodeGenerator\Sp_CodeGenerator\obj\x86\Debug\edmxResourcesToEmbed
我不确定这是否是巧合，但是一旦出现问题，我还注意到，一旦我打开 .config 文件，我就会收到几条关于元素 'entityFramework' 'defaultconnectionFactory' 'type' 等缺少架构的消息。
任何关于下一步看哪里的建议，非常感谢。
