I add from CodePlex called T4MVC.
This turns all your strings into a method call by using a combination of T4 templates and partial classes.
It will allow you to turn your ActionLink methods into a syntax checked method call.
@Html.ActionLink("Add Visit", "Create", "Visit", new { id = Model.Id }, null)
would be turned into
@Html.ActionLink("Add Visit", MVC.Visit.Create(Model.Id))
and
@Html.ActionLink("Add Visit", "Create", "Visit", new { id = Model.Id, Param2 = "Param2", Param3= "Param3Value" }, null)
@Html.ActionLink("Add Visit", MVC.Visit.Create(Model.Id, "Param2", "Param3Value"))
Its a life saver when you turn on compiled views.
