Bug on recurrence?

Create Weekly recurrence (also with your C# sample)

Weekly: Start 10.00, duration 30m, Recur Every 2 Week

Select all check from Monday to Sunday (ie all the week)

Range:Start 6/Nov/2006, No end Date.

----> we have this events:
 
 6, 7, 8, 9, 10, 11    (12 missing....Why)?

Next Week --> from 19 to 25.....

With OUTLOOK

the range is correctly: 6,7,8,9,10,11,12
Next week is 20,.....26

I think that the problem is First day of week: (monday)
Codejock output is the same as FirstDayofWeek =sunday...
