Introduction

In this article, we’ll discuss Views in ASP.NET MVC framework. In MVC, the views we refer to your views can be PDF, Html, text or anything else. But in a web application most of the time it is a team which is redundant and we see it’s razor engine supports it in a nice way.

here, we added this index action.

It is what we have in the first place. the index action uses the View method let’s say read and check it.

It will happen if we tested as it is in the browser.
