Is there something like RouteConfig.cs in .Net Core MVC?

Question

I'm trying to follow Adam Freeman's book "ASP .NET MVC". In this book there is chapter where author suggests putting routes to special configuration file App_Start/RouteConfig.cs. It looks like nice, but I'm trying to implement it with the help of .Net Core. I had not found special place for routes and I put routes into Startup.cs. But it looks like pretty ugly. Maybe somebody knows elegant solution for this case?

Here is code of my Startup.cs

public class Startup
{
    public Startup(IConfiguration configuration)
    {
        Configuration = configuration;
    }

    public IConfiguration Configuration { get; }

    // This method gets called by the runtime. Use this method to add services to the container.
    public void ConfigureServices(IServiceCollection services)
    {
        // services are here ..
    }

    public void Configure(IApplicationBuilder app, IHostingEnvironment env)
    {
        if (env.IsDevelopment())
        {
            app.UseDeveloperExceptionPage();
        }
        else
        {
            //app.UseExceptionHandler("/Home/Error");
            // The default HSTS value is 30 days. You may want to change this for production scenarios, see https://aka.ms/aspnetcore-hsts.
            app.UseHsts();
            app.UseHttpsRedirection();
        }

        app.UseStaticFiles();

        app.UseMvc(routes =>
        {
            // /
            routes.MapRoute(null, "", new
            {
                controller = "Products",
                action = "List",
                category = "", page = 1
            });

            // Page2
            routes.MapRoute(null,
                "Page{page}",
                new
                {
                    controller = "Products",
                    action = "List",
                    category = ""
                },
                new { page = @"\d+" }
            );

            // Category
            routes.MapRoute(null,
                "{category}",
                new
                {
                    controller = "Products",
                    action = "List",
                    page = 1
                });

            // Category/Page2
            routes.MapRoute(null,
                "{category}/Page{page}",
                new
                {
                    controller = "Products",
                    action = "List",
                },
                new
                {
                    page = @"\d+"
                });
        });
    }
}

P.S .Net Core version is 2.2

You can put them in another file:

public static class Routing
{
    public static void Include(IApplicationBuilder app)
    {
        app.UseMvc(routes =>
        {
            // /
            routes.MapRoute(null, "", new
            {
                controller = "Products",
                action = "List",
                category = "",
                page = 1
            });

            // Page2
            routes.MapRoute(null,
                "Page{page}",
                new
                {
                    controller = "Products",
                    action = "List",
                    category = ""
                },
                new { page = @"\d+" }
            );
        }
        );
    }
}

And then call it in the `Startup' class:

public class Startup
{
    ...
    public void Configure(IApplicationBuilder app, IHostingEnvironment env)
    {
        ...
        app.UseStaticFiles();
        Routing.Include(app);
        ...
    }
}

Is there something like RouteConfig.cs in .Net Core MVC?
