ASP.NET MVC Areas: How to hide "Area" name in URL?

Question

When running the MVC 2 Areas example that has a Blog Area and Blog Controller the URL looks like this:

http://localhost:50526/Blog/Blog/ShowRecent in the format:

RootUrl / AreaName / ControllerName / ActionName

Having just discovered MVC Areas, it seem like a great way to organise code, ie create an Area for each section, which in my case each section has its own controller. This means that each AreaName = ControllerName. The effect of this is the double AreaName/ControllerName path in the Url eg /Blog/Blog/ above

Not having a complete clear understanding of routing, how could I setup routing to not show the AreaName?

EDIT:

I am trying to reduce the amount of work with routes as these appear to effect each other (ie require specific ordering) and may cause major headaches :-) In converting an existing webform app to MVC, I have converted a couple of core sections, These have one Controller each and a fair amount of View/Actions and although most of the Data Access is code is in assemblies the number of Model/ViewData classes is growing... I am currently creating sub-folders in the Root Models/Views folders for these sections (or Areas) and was hoping that creating Areas would work the same way except having the code organised (with the use of a basic route that covers the Area) Any comment on this?

Inside each area's folder you'll see a *AreaName*AreaRegistration.cs file. This is where the area routeing rules are stored. By default, as they are generated, they will contain the area name ahead of everything else.. The problem is: if you remove the area name "folder" from the route, the route will catch all "standard" {controller}/{action}/{id} requests. Which is obviously not what you want..

To overcome this you can add the regex filters on the routes, based on the controller names present in that route. The drawback? You won't be able to have two controllers with the same name within the app (at least not using the standard route.. You can always think of a different route to access them :) )

In the end.. Having this structure:

/Areas
/Areas/Blog/Controllers/BlogController.cs
/Areas/Blog/Controllers/FeedController.cs
/Areas/User/Controllers/UserController.cs
/Controllers/PageController.cs

What you should have is sth like this: In BlogAreaRegistration.cs:

context.MapRoute(
    "Blog_default",
    "{controller}/{action}/{id}",
    new { action = "Index", id = UrlParameter.Optional },
    new { controller = "(Blog|Feed)" }
);

In UserAreaRegistration.cs:

context.MapRoute(
    "User_default",
    "{controller}/{action}/{id}",
    new { action = "Index", id = UrlParameter.Optional },
    new { controller = "(User)" }
);

In Global.asax.cs:

public static void RegisterRoutes(RouteCollection routes)
{
    context.MapRoute(
    "Default",
    "{controller}/{action}/{id}",
    new { controller = "Home", action = "Index", id = UrlParameter.Optional }
    );
}
protected void Application_Start()
{
    AreaRegistration.RegisterAllAreas();

    RegisterRoutes(RouteTable.Routes);
}

Note that in global.asax area registrations come first! :)

UPD: Based on your question update: There us one major thing that you'll have to take into consideration if you will use areas: If you have a inter-area link, you'll also have to provide the area name in the link. E.g.

<%: Html.ActionLink("Link text", "Action", "Controller", new { area = "Blog", id = 4, title = "page-title" }); %>

You get the idea.

Regarding the multiple models/views, at the moment I'm following a structure like this

/Code/ // helper, extension classes that aren't moved to libraries
/Models/Data/ // The EF classes + validation classes are here
/Models/ViewModels/{controller}/ // view models stored per controller

So far it works fine, and I managed to keep the solution relatively organised. As I stated, the only area that I created so far is the Admin area because it's that much different from the rest of the website :)
