I am new to sqlite entity framework 6.
I am trying to update a record in table but it not saving the changes in the database.
I am using the following code to Update Record.
public int saveBill(general_bills cat)
        {

            using (alldbEntities db = new alldbEntities())
            {
                if (cat.ID > 0)
                {
                    //db.Attach(cat);
                    //db.ApplyPropertyChanges("general_bills", cat);
                    //db.Attach(cat);

                    //db.AddTogeneral_bills(cat);
                    //db.Attach(cat);
                    //db.AcceptAllChanges();
                    db.AttachTo("general_bills", cat);
                    //db.Entry(cat).State = EntityState.Modified;
                    db.SaveChanges(true);
                }
                else
                {
                    db.AddTogeneral_bills(cat);
                    db.SaveChanges(true);

                }
                return (int)cat.ID;
            }
        }

Please try is as below.

Note : I hope your cat entity collection is "AddTogeneral_bills"

public int saveBill(general_bills cat)
        {

            using (alldbEntities db = new alldbEntities())
            {
                if (cat.ID > 0)
                {

            var catObj = (from c in db.AddTogeneral_bills
                                    where c.ID=cat.ID
                                    select c).FirstOrDefault();


                   catObj.pro1= cat.pro1;
                   catObj.pro2= cat.pro2;
                   //put your properties

                   db.SaveChanges();
                }
                else
                {
                    db.AddTogeneral_bills.Add(cat);
                    db.SaveChanges();

                }
                return (int)cat.ID;
            }
        }
