I created a simple silverlight web application to test deployment. The page just contains a xaml button. It deploys fine, but when I try to access the website, it tells me that it could not load file or assembly System.Web.Mvc.... I don't even see this reference in my Silverlight app to begin with.
I got it to work For some reason, the silverlight app was looking for System.Web.Mvc. I just deleted everything and re-published and it worked fine.
