提问by Kirsten Greed
My WPF application works fine on Windows 7, but throws the above error when running on Windows XP. I am using ENtity Framework 6.1.1
我的 WPF 应用程序在 Windows 7 上运行良好，但在 Windows XP 上运行时会引发上述错误。我正在使用实体框架 6.1.1
App.xaml is
App.xaml 是
<Application.Resources>

<Setter Property="Margin" Value="6,2,6,2"/>
</Style>
<Style x:Key="DetailsOuterGridStyle" TargetType="Grid">
<Setter Property="Background" Value="White"/>
</Style>
</Application.Resources>
The inner exception is
内部异常是
System.Configuration.ConfigurationErrorsException: An error occurred creating the configuration section handler for entityFramework: Request failed.

The app.config contains the correct connection string. Could it be interpreted differently on XP?
app.config 包含正确的连接字符串。它可以在 XP 上有不同的解释吗？
[Update] The code fails when initialising the connection.
[更新] 初始化连接时代码失败。
var connect = new CartConnect(constr);

我设置我的连接字符串使用

string constr = ConfigurationManager.ConnectionStrings[key].ConnectionString;
var connect = new CartConnect(constr); // fails here
connect.Configuration.LazyLoadingEnabled = false;

return connect;

I looked at other questions on "An error occurred creating the configuration section handler for entityFramework"
我查看了有关“为 entityFramework 创建配置节处理程序时出错”的其他问题
I tried removing and re-adding Entity Framework using NuGet
我尝试使用 NuGet 删除和重新添加实体框架

Thank you ErikEJ. Copying the files locally works. I wonder if there is a way to get it working on the network?
谢谢 ErikEJ。在本地复制文件有效。我想知道是否有办法让它在网络上工作？
Reminds me of my problem in this question about regasm
让我想起我在这个关于 regasm 的问题中的问题

Is the Q: drive local? If not, try to run the app from a local drive - the error message indicates that there is a security issue preventing you to run from a network folder.
Q：驱动是本地的吗？如果没有，请尝试从本地驱动器运行该应用程序 - 错误消息表明存在安全问题，阻止您从网络文件夹运行。
