How to configure routers in two applications?

Question

ASP.NET

Created several projects, one admin panel, the other just an application.
When I run the solution, only the admin route is processed

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.Mvc;
using System.Web.Routing;

namespace IQS
{
    public class RouteConfig
    {
        public static void RegisterRoutes(RouteCollection routes)
        {
            routes.IgnoreRoute("{resource}.axd/{*pathInfo}");

            routes.MapRoute(
                name: "Admin",
                url: "Admin/{controller}/{action}/{id}",
                defaults: new { controller = "Service", action = "Index", id = UrlParameter.Optional }
            );
        }
    }
}

and I can’t get another application at all, 404.

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.Mvc;
using System.Web.Routing;

namespace Widget
{
    public class RouteConfig
    {
        public static void RegisterRoutes(RouteCollection routes)
        {
            routes.IgnoreRoute("{resource}.axd/{*pathInfo}");

            routes.MapRoute(
                name: "Default",
                url: "Widget/{controller}/{action}/{id}",
                defaults: new { controller = "Service", action = "Index", id = UrlParameter.Optional }
            );
        }
    }
}

Project structure:

I have no experience in mvc so I can't figure out how to solve problems, maybe area maybe namespace..

Answer 1

Why have separate projects been created?
Use one project, and in it already create areas (Areas) for the admin panel and the application itself.
