Answer 1

Finally, a solution. :)

var date = DateTime.Now; // It can be any day
var lastBalances = (from a in context.AccountBalanceByDate
        where a.Date < date
        group a by new {a.AccountId} into g
        select g.OrderByDescending(a => a.Date).FirstOrDefault() into r
        select new
        {
            Id = r.Id,
            AccountId = r.AccountId,
            Date = r.Date,
            Balance = r.Balance
        }).ToList();

You wanted it in LINQ, but personally, I might of kept the SQL for maintainability.
