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 ?? "");<# } #>
