Indeed we made some changes on how the Recurrence pattern works. The old properties StartHour/StartMinute and EndHour/EndMinute are now automatically obtained from the item the recurrence is associated with. The StartDate property of the recurrence specifies the date from which the recurrence should start, that is, the date of the first item occurrence. The EndDate property specifies the date when the recurrence should, and is only used if the RecurrenceEnd is set to EndDate.

In general, StartDate and EndDate of the recurrence pattern define the time interval where the occurrences of this recurrence will appear. The length of each occurrence and its relative start and and times are automatically obtained from the original item.

I was talking about setting up the recurrence programmatically as well. Lets say you have an item which starts at 10:00 AM on 21st of November, 2007 and ends at 12:00 AM on the same day. In order to make this item recurrent (with the first occurrence being the item itself), you create the following recurrence (a references the item being made recurrent):

// Create the recurrence
Recurrence r = new Recurrence();
r.StartDate = a.StartTime.Date;
r.Pattern = RecurrencePattern.Daily;
r.Days = 2;
r.RecurrenceEnd = RecurrenceEnd.Never;

// Assign the recurrence
a.Recurrence = r; 

As you can see, the recurrence pattern is defined much more easily than it was in the previous versions. Also notice that the EndDate property is never used, since the recurrence is infinite.
