What is Controller in ASP.NET MVC

As you know an MVC application consists of three parts: model, view, and controller. The development of a web application usually required the knowledge of all the three parts.
In ASP.NET MVC Controllers are responsible for processing an incoming user request, executing the appropriate application code and communicating with the model, and rendering the required view.

                            How to Create Controller.
