Unable to view design in UWP

I am a beginner in UWP app and facing issues in a very initial stage of writing my “Hello world” program.

I am trying to create a new project of type “BlankApp (Universal Windows)”. After the new project got created I cant able to see the designer of XAML, its displaying only the XAML script.

In WPF projects the designer is loading properly. The screen shots are given below displaying the steps I have followed.
