title: How to run Angular 5 asp.net core MVC on Internet Explorer 11
body: <p>I created a basic Angular application on VS 2017 under ASP.NET core 2 and upgraded it to Angular 5. It should run on IE 11, but I notice that it's not working properly on IE11; it works on Chrome. When I read I saw we should do something on <code>polyfill.ts</code> but with ASP.NET core I can't see any polyfill file.</p>
  
  <p>Would you tell me how I can achieve this?</p>
