ASP.NET MVC: Change Admin URL to More User Friendly URL With Routing

In the previous post we created a Admin Area, however we had to type in localhost/Admin/Home/Index to get to the Admin index page.  In this post we are going to make the Index page more user friendly.

To do that first let's assign the namespace to a local variable so that we can use it in multiple routes.

Open the "AdminAreaRegistration.cs" file in the /Areas/Admin folder and change the RegisterArea method to the following:

        public override void RegisterArea(AreaRegistrationContext context) 
        {
            var namespaces = new string[] { typeof(NorthwindCafe.Areas.Admin.Controllers.HomeController).Namespace };

            context.MapRoute(
                "Admin_default",
                "Admin/{controller}/{action}/{id}",
                new { action = "Index", id = UrlParameter.Optional },
                namespaces 
            );
        }

Fedora: Install Eclipse IDE

Love it or hate it the Eclipse IDE is a comprehensive development tool that rivals or surpasses Microsoft's Visual Studio.  If you are working outside of the .NET stack Eclipse will probably have plug-in for your development platform. I myself find the UI a little bit overwhelming.  But for the price it's a pretty good value, which is free!

Here are the steps to install the Eclipse IDE on your Fedora instance:

1.  Log into your Fedora instance, and open a terminal session
2.  Type sudo su to switch to super user priviledges
3.  Now type sudo dnf install eclipse to install Eclipse
