title: App.Config file not working as expected with Selenium c#
body: <p>I am attempting to use app.config for commonly used values and I cannot get the values into the browser. As far as my code is concerned its fine, no issues according to my previous research however it simply returns the value but doesnt use it in the browsers URL. </p>
  
  <p>Code within test: 
  <code>string URL = ConfigurationManager.AppSettings ["URL"].ToString();</code> </p>
  
  <p>App.config:</p>
  
  <p><code>&lt;add key="URL" value="https://www.google.co.uk"/&gt;</code></p>
  
  <p>the config is sat amongst the usual   etc so i know its not because of case sensitive mistakes. </p>
