Question

我有以下生成的EF模型使用的连接字符串。它在我的本地计算机上正常工作但是当我部署时，我得到以下错误。我在SO上看了多次引用的网址：http://blogs.teamb.com/craigstuntz/2010/08/13/38628/如果它有答案，我就不会看到它。

我正在粘贴下面的错误

  <add name="svcodecampEntitiesAllTables" connectionString="metadata=res://*/EFModel.ModelAllTables.csdl|res://*/EFModel.ModelAllTables.ssdl|res://*/EFModel.ModelAllTables.msl;provider=System.Data.SqlClient;provider connection string=&quot;data source=.;initial catalog=svcc;integrated security=True;persist security info=True;multipleactiveresultsets=True;application name=EntityFramework&quot;" providerName="System.Data.EntityClient" />

Answer 1

我也有这个问题。我通过显式命名包含模型的程序集来修复它。

因此，如果您的模型位于“Product.DAL.dll”中，而不是：

  metadata=res://*/EFModel.ModelAllTables.csdl|...

放：

  metadata=res://Product.DAL/EFModel.ModelAllTables.csdl|...

用于所有3个元数据资源

Answer 2

您必须添加对包含edmx图的项目的引用，并更改Nunit项目中的连接字符串

更改

<add name="ContainerName" connectionString="metadata=res://*/Diagram.csdl|re.....

通过元数据中3个位置的库名称

<add name="ContainerName"connectionString="metadata=res://File.Data/Diagram.csdl|res://File.Data/Diagra...

“File.Data”是File.Data.dll，由包含图表的项目生成的库

Answer 3

我有同样的问题并通过运行自定义工具解决了。右键单击 Model.tt 文件并单击运行自定义工具并对 context.tt 文件和 Model.edmx 文件重复相同的操作。重新构建应用程序将起作用。

EF给我生产错误而不是Dev。
