Question

我有一个包含2个项目的解决方案：asp app和console app。在我的asp项目的web.config中，我有这个： <connectionStrings> <add name="con" connectionString="Data Source=PC-Flo\SQLExpress2008;Initial Catalog=test;Persist Security Info=True;User ID=lol;Password=lolation" providerName="System.Data.SqlClient" /> </connectionStrings>

和我的联系有效。

现在我想连接我的控制台应用程序，所以在我的App.config中我放了同样的东西，但我有这个例外：

'System.Data.Entity.Internal.AppConfig'的类型初始值设定项抛出异常

感谢您的帮助。

App.config文件：

<?xml version="1.0" encoding="utf-8"?>
<configuration>
<connectionStrings>
    <add name="con" connectionString="Data Source=PC-Flo\SQLExpress2008;Initial Catalog=test;Persist Security Info=True;User ID=lol;Password=lolation" providerName="System.Data.SqlClient" />
</connectionStrings>
  <configSections>
    <!-- For more information on Entity Framework configuration, visit http://go.microsoft.com/fwlink/?LinkID=237468 -->
    <section name="entityFramework" type="System.Data.Entity.Internal.ConfigFile.EntityFrameworkSection, EntityFramework, Version=6.0.0.0, Culture=neutral, PublicKeyToken=" requirePermission="false" />
  </configSections>
  <entityFramework>
    <defaultConnectionFactory type="System.Data.Entity.Infrastructure.LocalDbConnectionFactory, EntityFramework">

我删除了所有文件，只是把它放在

中

<?xml version="1.0" encoding="utf-8"?>
<configuration>
    <configSections>

    </configSections>
    <connectionStrings>
        <add name="con" connectionString="Data Source=PC-Flo\SQLExpress2008;Initial   Catalog=test;Persist Security Info=True;User ID=lol;Password=lolation" providerName="System.Data.SqlClient" />
    </connectionStrings>

</configuration>

最后它有效。谢谢你的帮助。
