Answer 1

You could try a simple method of just counting the days. If this is usually done for periods of time like months and not years and isn't called repeatedly then this will not be a performance hit to just walk it.

int GetWorkingDays(DateTime startDate, DateTime endDate)
{
    int count = 0;
    for (DateTime currentDate = startDate; currentDate < endDate; currentDate = currentDate.AddDays(1))
    {
        if (currentDate.DayOfWeek == DayOfWeek.Sunday || currentDate.DayOfWeek == DayOfWeek.Saturday)
        {
            continue;
        }
        count++;
    }
    return count;
}
