EntityState belongs to System.Data.Entity namespace, not System.Data. But in your code you have used it like System.Data.EntityState

You already have a using statement for System.Data.Entity namespace on the top part of your file. So you you do not need the fully qualified name. you may simply use EntityState.Modified

Replace

context.Entry(line.Product).State= System.Data.EntityState.Modified;

with

context.Entry(line.Product).State= EntityState.Modified;
