protected override void OnModelCreating(DbModelBuilder modelBuilder)
{
modelBuilder.Entity<childtable>().HasRequired(m => m.ParentTable).WithMany(m => m.ChildTable).WillCascadeOnDelete(true); //Line1

modelBuilder.Entity<childtable>().HasRequired(m => m.ParentTable).WithMany(m => m.ChildTable).HasForeignKey(m => m.EmailCampaignId).WillCascadeOnDelete(true);//Line2
base.OnModelCreating(modelBuilder);
}
for cascade delete which one i have to use Line1 or Line2 as per my understanding both are doing same thing. is there any difference between Line1 code and Line2 code
