Question

我尝试使用此配置数据向WCF服务消息添加跟踪器我使用SvcConfigEditor.exe添加了跟踪器，这里是web.config生成的文件

    </sharedListeners>
    <trace autoflush="true" />
  </system.diagnostics>

</configuration>

但是当我尝试运行WCF测试客户端时，我得到以下异常

由于相关，无法访问请求的页面   页面的配置数据无效。

配置部分＆＃39; entityFramework＆＃39;无法读取，因为它缺少部分声明

我真的不知道为什么会抛出这个异常

Answer 1

因为entityFramework标记不是.NET的标准。你需要告诉它如何解释它。

为此，请在文件中添加以下部分（例如在<connectionStrings>之前添加：

<configSections>
    <section name="entityFramework" type="System.Data.Entity.Internal.ConfigFile.EntityFrameworkSection, EntityFramework, Version=6.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" requirePermission="false" />
</configSections>
