title: Where are @Json.Encode or @Json.Decode methods in MVC 6?
body: <p>What is equivalent of MVC5's <code>@Json.Encode</code> method in MVC6? In MVC5 we can access those methods in views. But I can't find any methods which I can access from MVC 6 views.</p>
  
  <p>I don't want to write a helper method if there is already a built in feature in MVC6.</p>
