The name 'EntityState' does not exist in the current context
Try changing
e.g.
System.Data.EntityState.Modified;
to
System.Data.Entity.EntityState.Modified;
(Not sure what's going on. Did Microsoft change the package?)
When I had this problem, I fixed it by including the namespace it's from:
using System.Data;
