I need help, how can I do this in Umbraco 8.

I am following this tutorial for Umbraco 7 made by Kevin Giszewski.

using Umbraco.Core;

namespace MyNamespace
{
    public class RegisterViewEngine : ApplicationEventHandler
    {
        protected override void ApplicationStarting(UmbracoApplicationBase umbracoApplication,
            ApplicationContext applicationContext)
        {
            System.Web.Mvc.ViewEngines.Engines.Add(new MyViewEngine());

            base.ApplicationStarting(umbracoApplication, applicationContext);
        }
    }
}
