T4MVC @Url.Action(MVC.Controller.Action()) Renders “?Area=” Parameter in QueryString

Question

I am rendering a menu from a Partial Action directly to the layout, using:

@Html.Action(MVC.Menu.Index())

This action, determines which Men

Answer 1

Something strange is going on here, and I wonder if there is some kind of MVC bug at the root. Even without using T4MVC, this happens if you write:

@Html.ActionLink("Welcome", "Index", "Home", new { Area = "" }, null)

In a regular view, this doesn't generate the bogus ?Area=, while in a Html.Action call it does. I need to ask someone on the team.

For now, you can workaround by deleting this line (around line 310) in t4mvc.tt:

<# if (MvcVersion >= 2) { #>result.RouteValueDictionary.Add("Area", area ?? "");<# } #> 

Answer 2

I solve this issue in a very easy way, simply by adding to all routes that are not in area empty area route like this:

routes.MapRoute(
"Default",
"{controller}/{action}/{i​d}",
new { controller = "Home", action = "Index", area = "", id = UrlParameter.Optional });
