Install Nuget package.

To start with asp .net friendly urls you need to install following Nuget package.

                Install-Package Microsoft.AspNet.FriendlyUrls

Files installed by friendly urls in asp .net

Nuget will automatically install following files and folders in your application:

 



 

Note: "Site.Mobile.Master" and "ViewSwitcher.ascx" are optional files you can delete these files if not required.

Add Global.asax file.

Add Global.asax file in your application and add following lines of code:

            void Application_Start(object sender, EventArgs e)
            {
               RouteConfig.RegisterRoutes(System.Web.Routing.RouteTable.Routes);
            }
        

Add new pages and test application

This is all you need to remove .aspx from url in asp .net. Add 2 new pages to test the application. Here I have used "Default.aspx" and "About.aspx".
