title: How to store app settings(App.config) in Xamarin
body: <p>I am just getting started on Xamarin and decided to use Xamarin Forms. Traditionally in .Net projects we have a app.config or web.config. How is this done for Mobile applications.</p>
  
  <p>And how are the settings updated for each environment. I have used config transforms. Is there anything similar in Xamarin?</p>
