Code:
                    ConfigurationFileMap fileMap = new ConfigurationFileMap(CONFIG_PATH);
                    Configuration configuration = System.Configuration.ConfigurationManager.OpenMappedMachineConfiguration(fileMap);
                    value = configuration.AppSettings.Settings[key].Value;

Config File:

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
  <appSettings>
    <add key="FeedCacheTime" value="300" />

you can add this to the configuration file you wish to read:
<configuration>
  <configSections>
    <section name="appSettings"
                type="System.Configuration.AppSettingsSection"/>
  </configSections>
  <appSettings>.....

Open in new window


Once you've done that your code should work fine.
