entity framework No LOCK

Does following entity framework code implements WITH (NOLOCK) by default.

if not how can I add it.

        public List<String> GetClientsList()
        {
            using (var context = new CMContainer())
            {
                return context.Clients.Select(col => col.ClientNo).ToList(); 
            }
        }

Select allOpen in new window

is this good option to follow i.e. WITH (NOLOCK)  when only 100 concurrent select is required and nothing else
