I made some changes on my db using SQL Mangamnet Studio. And everything is fine there. But when I open Visual studio, going to my model .edmx open diagram, right clik-> "Update model from database..." I got this http://postimg.org/image/4vsbg0k8d/ , but I can't select anything to update. When I click "Finish", it don't update anything.
EDIT: I added new table to database, if it means anything.
