Multiple types were found that match the controller

I'm starting to make use of the new Areas feature in my MVC 2 applications. I've found it great for separating my applications into distinct sections rather than staring at a massive list of controllers/views all bundled into one folder. I came across an issue when I created a controller with the same name as a controller within a different or the default area:

Multiple types were found that match the controller named XXXXXXXX...

I thought it was a little cheap of Microsoft requiring you to give your controllers unique names across all areas. I was relieved to find out giving the same name within different areas is perfectly OK, you just need to specify the full namespace for the controller when setting up the route for it, like so:

public override void RegisterArea(AreaRegistrationContext context)
{
 context.MapRoute(
  "Members_default",
  "Members/{controller}/{action}/{id}",
  new { controller = "Home", action = "Index", id = UrlParameter.Optional },
  new string[] { "MyWebApp.Areas.Members.Controllers" }
 );
}

I knew Microsoft wouldn't let me down ;)
