I have a database first ASP.NET MVC 5 EF6 project. I\'m using VS2015 CE. When I change my database (SQL Server 2012), I then go to VS to update my edmx file like this:

Answer 1

I've had this issue on a number of occasions. For simple problems I've edited the edmx file by opening in the code editor ( Open With... > Source Code (Text) Editor ).

Locate the table by looking for by searching for EntityType Name="your table name".

Typically I see an entry that doesn't look right, delete it, save and close the file. Open the edmx the usual way and refresh the model and Presto problem solved.
