We just created an ASP.NET MVC controller and added a view for an Index action in the controller. Now we need to configure routing for the ASP.NET MVC application so that any request to the Index action is handled by the ASP.NET MVC router. Follow these steps to configure ASP.NET MVC routing:

1. Open Startup.cs.
2. Comment or remove the app.UseDefaultFiles() statement from the Configure method as we will serve views using ASP.NET MVC.
3. Replace the app.UseMvc() statement in the Configure method with this one:

     app.UseMvc(config =>   
            {   
              config.MapRoute(   
              name: "Default",   
              template: "{controller}/{action}/{id?}",   
     defaults: new   { controller = "Home", action =    
     "Index" }   
               );   
            });

Here, we have added the default routing for ASP.NET MVC. Any request to the Web API is mapped with the HTTP verbs or actions in the controller.
