I'm having an issue creating a task for last week of the selected months.
I searched the discussions and found a thread back in 2009 with a similar issue, except it dealt with FifthWeek.
new MonthlyDOWTrigger is expecting 3 parameters.
If I pass WhichWeek.LastWeek - I get an exception saying only one single week is allowed.
If I pass some other week and then set RunOnLastWeekOfMonth = true - the task gets created for the last week and other week that has been passed when object was initialized.
Basically it's not allowing me to set last week only.
