Can I make ASP.NET MVC Html.RouteLink() return a url for my home page without an ID?

Answer 1

Add a new route before your "IdOnly" route for the home page:

routes.MapRoute( _
    "HomePage", _
    "", _
    New With {.controller = "Page", _
              .action = "Details", _
              .id = "7"} _
)

RouteLink will use the first matched mapping in the routing table to generate the link.
