title: Asp.Net MVC: How do I get virtual url for the current controller/view?
body: <p>Is it possible to get the route/virtual url associated with a controller action or on a view?  I saw that Preview 4 added LinkBuilder.BuildUrlFromExpression helper, but it's not very useful if you want to use it on the master, since the controller type can be different.  Any thoughts are appreciated.</p>
