c# - 'System.Data.Entity.Internal.AppConfig' 的类型初始值设定项引发了 Windows XP 异常

Question

我的 WPF 应用程序在 Windows 7 上运行良好，但在 Windows XP 上运行时抛出上述错误。我正在使用 Entity Framework 6.1.1

App.xaml 是

<Application.Resources>
    <main:MainConverter x:Key="MainVerter"/>
    <Style x:Key="DetailHead1Style" TargetType="TextBlock">
        <Setter Property="FontSize" Value="20"/>
        <Setter Property="FontWeight" Value="Bold"/>
        <Setter Property="Foreground" Value="DarkSlateGray"/>
        <Setter Property="Opacity" Value="0.8"/>
        <Setter Property="FontStyle" Value="Italic"/>
        <Setter Property="Margin" Value="6,2,6,2"/>
    </Style>
    <Style  x:Key="DetailsOuterGridStyle" TargetType="Grid">
        <Setter Property="Background" Value="White"/>
    </Style>
</Application.Resources>

内部异常是

System.Configuration.ConfigurationErrorsException: An error occurred creating the configuration section handler for entityFramework: Request failed. 
(Q:\devnet10\SBD.CartBrowser\SBD.CartBrowser\bin\Debug\SBD.FlightControl.exe.Config line 23) ---> System.Security.SecurityException: Request failed.

       at System.Configuration.BaseConfigurationRecord.CallCreateSection(Boolean inputIsTrusted, FactoryRecord factoryRecord, SectionRecord sectionRecord, Object parentConfig, ConfigXmlReader reader, String filename, Int32 line)

app.config 包含正确的连接字符串。在 XP 上会有不同的解释吗？

[更新]初始化连接时代码失败。

 var connect = new CartConnect(constr);

[更新]

app.config 是

 <?xml version="1.0" encoding="utf-8"?>
<configuration>
  <configSections>
    <section name="entityFramework" type="System.Data.Entity.Internal.ConfigFile.EntityFrameworkSection, EntityFramework, Version=6.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" requirePermission="false"/>
  </configSections>

  <connectionStrings>
    <add name="CartConnect_HAPPY4" connectionString="metadata=res://*/Edm.CartModel.csdl|res://*/Edm.CartModel.ssdl|res://*/Edm.CartModel.msl;provider=System.Data.SqlClient;provider connection string=&quot;Database=mydatabase;Server=Server15\SQLExpress;Integrated Security=False;User=mylogin;Password=mypassword;MultipleActiveResultSets=True;App=EntityFramework&quot;" providerName="System.Data.EntityClient"/>
  </connectionStrings>

  <entityFramework>
    <defaultConnectionFactory type="System.Data.Entity.Infrastructure.LocalDbConnectionFactory, EntityFramework">
      <parameters>
        <parameter value="v11.0"/>
      </parameters>
    </defaultConnectionFactory>
    <providers>
      <provider invariantName="System.Data.SqlClient" type="System.Data.Entity.SqlServer.SqlProviderServices, EntityFramework.SqlServer"/>
    </providers>
  </entityFramework>

   <startup>
    <supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.0"/>
   </startup>

</configuration>

我使用

设置我的连接字符串

private CartConnect MakeConnect()
{
    string key = string.Format("CartConnect_{0}", Environment.MachineName.ToUpperInvariant());
    string constr = ConfigurationManager.ConnectionStrings[key].ConnectionString;
    var connect = new CartConnect(constr); // fails here

    connect.Configuration.LazyLoadingEnabled = false;

    connect.Configuration.ProxyCreationEnabled = false;

    return connect;
}

我查看了有关“为 entityFramework 创建配置部分处理程序时发生错误”的其他问题

我尝试使用 NuGet 删除并重新添加 Entity Framework

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运行？

让我想起我的问题 in this question about regasm

Q: 驱动器是本地的吗？如果不是，请尝试从本地驱动器运行该应用程序 - 错误消息表明存在阻止您从网络文件夹运行的安全问题。
