Answer 1

Based on DeBorges answer, here is an extension to get any specific Day

public static DateTime GetLastSpecificDayOfTheMonth(this DateTime date, DayOfWeek dayofweek)
    {
        var lastDayOfMonth = new DateTime(date.Year, date.Month, DateTime.DaysInMonth(date.Year, date.Month));

        while (lastDayOfMonth.DayOfWeek != dayofweek)
            lastDayOfMonth = lastDayOfMonth.AddDays(-1);

        return lastDayOfMonth;
    }
