Hi,pmdrait

404 error means you have routed to an page which is not exist.

You can share your routing code and the related actions if it has, so we can check it.

Hi,pmdrait

Try to change your endpoints to:

endpoints.MapControllerRoute(
                    name: "default",
                    pattern: "{controller=Home}/{action=Index}/{id?}");

Or the url: '/Papers/Edit/Id=1',  will be 404.
