Entity exception

try

                    {

                        // Your code...

                        // Could also be before try if you know the exception occurs in SaveChanges

                        db.SaveChanges();

                    }

                    catch (DbEntityValidationException e)

                    {

                        foreach (var eve in e.EntityValidationErrors)

                        {

                            ;

                        }

                    }

Could not find an Entity Framework project type to add to the Solution. Turns out I need to add a code project first. 

Project type - Class Library but not the .NET Core Class Library. Then within that project I was able to add from Data tab a new Entity Framework item.
