<appSettings>

  <add key="webpages:Version" value="3.0.0.0"/>

  <add key="webpages:Enabled" value="false"/>

  <add key="ClientValidationEnabled" value="true"/>

  <add key="UnobtrusiveJavaScriptEnabled" value="true"/>

  <add key="AppVersion" value="1.0"/>

</appSettings>

　　web.config：

<appSettings configSource="Configs\AppSettings.config"></appSettings>

　　读取配置：

System.Configuration.ConfigurationManager.AppSettings["AppVersion"]
