I managed to create a Model First DBContext model (before it was a normal ObjectContext derived model).
Strangly now my VS is not showing ANY of my classes in the Mo
I just experienced this issue in a project that had been working. There were NO updates to EF or MVC, it just started throwing the "There no model classes..." message. I backed up my project, deleted it from my HD and the got the most recent version from source control, SVN in this case. I rebuilt the project and now it works again, just like magic.
VS 2012 EF 5.0 .NET 4.5 MVC 4.0
