How to make that all requests lead to one controller and action (with the exception of static and api, which I will indicate)? Since my factual routing is done by JavaScript on the client, I want to display the same View on any query

    routes.MapRoute( name: "Default", url: "{*catchall}", defaults: new { controller = "Home", action = "Index" } );

    Try this: "{*catchall}" (exactly with an asterisk) will allow you to intercept the request with any number of segments, in defaults write the values ​​that you need. Since the route is quite common - it is better to put it the latest

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

      and for api

       routes.MapHttpRoute( name: "API Default", routeTemplate: "api/{controller}/{id}", defaults: new { id = RouteParameter.Optional });
