title: Program cannot find app.config
body: <blockquote>
    <p>// Set LastRun to now<br>
                config.AppSettings.Settings["LastRun"].Value = DateTime.Now.ToString();
                // Save all settings
                config.Save(ConfigurationSaveMode.Modified);</p>

  <p>This code was working fine in my development server but not in my production server. It seems like my program is unable to communicate with my app.config file. I have checked all the "obvious" . . Any ideas ... ?  </p>
