ASP.NET IIS 7 中带有 EF 6.1.3 的应用
ASP.NET app with EF 6.1.3 in IIS 7
我们刚刚设置了一个新的 PCI 兼容服务器，当我将我的 asp.net 应用程序部署到它时，我收到此错误消息：
具有不变名称 'System.Data.SqlClient' 的 ADO.NET 提供程序未在计算机或应用程序配置文件中注册，或者无法加载。有关详细信息，请参阅内部异常。
我仔细检查了我的配置文件，卸载了 EF 并在所有项目中重新安装了它。部署后我在 bin 文件夹中看到了 DLL（我们对 team city 和 octopus 使用 CI）。我在线检查了几乎所有 post 的解决方案，但都没有成功。
当我将此应用程序部署到不符合 PCI 的服务器时，它工作正常。我不知道是什么原因造成的！！

任何人 运行 通过这个，终于弄明白了。
在 machine.config 文件中：
32 位
%windir%\Microsoft.NET\Framework\[version]\config\machine.config
64 位
%windir%\Microsoft.NET\Framework64\[version]\config\machine.config
定义了一个 dbproviders 部分，但紧随其后的是另一个这样定义的部分 <DbProviderFactories/>
删除第二个应用程序后，该应用程序便开始运行，并且上述错误不再出现。
问题仍然是为什么机器配置会定义两个部分。没有人手动编辑此文件！！
