我不幸地将 EntityFramework 代码从 .NET WebProject迁移到 .NET WebSite。我已将引用的站点与项目匹配，并确认引用在 web.config 中，但我仍然缺少对System.Data.Objects和System.Data.Objects.DataClasses的引用

错误：

Error   203 The type or namespace name 'Objects' does not exist in the namespace 'System.Data' (are you missing an assembly reference?)

网络配置：

我不认为这是一个修复，而是一个有效的黑客。

- 进行项目并将目标框架从 4 应用到 3.5 - 进行了更改，然后恢复到目标框架 4

using System.Data.Objects
using System.Data.Objects.DataClasses

工作中。

有一个类似的问题，在添加正确的实体框架后消失了web.config/App.config

<configuration>
  <configSections>
      <section name="entityFramework" type="System.Data.Entity.Internal.ConfigFile.EntityFrameworkSection, EntityFramework, Version=5.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" requirePermission="false" />
    </sectionGroup>
  </configSections>
