Answer 1

from v in visits
join m in members on v.member_id equals m.member_id
where v.visit_Date >= startDate && v.visit_Date <= endDate
group m by new {  m.member_firstname, m.member_lastname, m.member_id } into g
orderby g.Count()
select new
{
   count = g.Count(),
   member_firstname = g.Key.member_firstname, 
   member_lastname = = g.Key.member_lastname,
   member_id = = g.Key.member_id,
}
