title: angular 2 CLI live reload is not working
body: <p>I am creating angular 2 application through "angular-cli" version "1.0.0-beta.28.3".</p>
  
  <p>When I am using commands "npm start" or "ng serve", the app is working at 
  <a href="http://localhost:4200" rel="nofollow noreferrer">http://localhost:4200</a></p>
  
  <p>But, when changing some code for type Script file or CSS, the live refresh for  browser is not happening. What's wrong here? Thanks!</p>
