Unrecognized configuration section compilation

Question

I am getting a Unrecognized configuration section compilation exception when adding

<?xml version="1.0"?>
<configuration>
  <configSections>
.....

  <compilation debug="true" targetFramework="4.0">
    <assemblies>
      <add assembly="System.Data, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" />
    </assemblies>
  </compilation>

this to my app.config

how do I add this to an app.config associated with a windows service?

<compilation>必须是<system.web>元素的子元素-有关更多信息，请参见http://msdn.microsoft.com/zh-cn/library/s10awwz0.aspx 。
