I'm looking at Haacks article here - http://haacked.com/archive/2009/07/31/single-project-areas.aspx
When I download the sample I get the following errors in the Global.ascx
Error 1 'System.Web.Routing.RouteCollection' does not contain a definition for 'MapAreaRoute' and no extension method 'MapAreaRoute' accepting a first argument of type 'System.Web.Routing.RouteCollection' could be found (are you missing a using directive or an assembly reference?)
I assume I am obviously missing somthing, anyone any ideas what?
