title: Changes in App.config do not reflect after restarting the application
body: <p>I am using an app.config file to store the dynamic parameters of my application. The problem is, when I change a value in app.config file, and start the application, it doesn't load the new value from config file. Seems like the values in app.config file are being read and embedded in exe file only at compile time! </p>
  
  <p>This is how I read the config file:</p>
  
  <pre><code>public class Helper
  {
      static Helper()
      {
          Foo = ConfigurationManager.AppSettings["Foo"];
      }
      public static string Foo { get; set; }
  }
  </code></pre>
  
  <p>Am I missing something?</p>
