Where has the generic html controls and url helpers gone ?
You know the ones that looked something like this:
this.TextBox<MyInputModel>(model=>model.Name)
this.ActionLink<MyController>(controller=>controller.Index)
They are extensions located in the assembly Micosoft.Web.MVC. You have to add this assembly to your project and add a reference to it in the web.config file. You should consult the following answer for more details: Where to get Microsoft.Web.Mvc.dll
