I have a Tasks list in my team site. I need to enable send email notification so that when a task is assigned or changed the

task owner should get an email notification. Go to team site => Tasks list => List Settings => Advanced Settings. You can find

an option to enable the send email notification.

        {
            using (SPSite site = new SPSite("https://serverName/sites/vijai/"))
            {
                using (SPWeb web = site.OpenWeb())
                {
                    SPList list = web.Lists.TryGetList("Tasks");
                    if (list != null)
                    {
                        list.EnableAssignToEmail = true;
                        list.Update();
                    }
                }
            }
        }
    }
}
