Issue routing default route in MVC with Attribute Routes

Question

I am trying to find out why the routing of these two sittuations are not functioing. I want to conver this rout in the Routes.config file to a route attribute. It needs to be a default, because when you just load the site, without any url entered, it needs to hit /Home/Index action.

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

I added this to the Home controller for the actionResult Index(), but it didn't work. Said no document loaded.

[Route]
[Route("~/", Name = "default")]
public ActionResult Index()
{
    var environmentsSharedAccounts = new List<EnvironmentSharedAccountVM>();


    return View(environmentsSharedAccounts);
}

Why does this now not resolve. Thanks in advance. BTW. I am finding, that the books I have read, and the examples I have seen are seeming to be more compleicated to me then I thought I guess, because this routing has been giving me issues. I think I understand it, but it doesn't work how expected. Anyways....

Answer 1

Try

[Route("")]
public ActionResult Index() 
....

Do you have this line on WebApiConfig.cs :

config.MapHttpAttributeRoutes();

?
