It seems that I may have partially found the problem, which then leads into another problem.
The recurrence rule given to me by the WinForms RadScheduler does not work in the ASP.Net RadScheduler.
WinForms RadScheduler gives me a RecurrenceRule of, "FREQ=DAILY;UNTIL=20120905T000000Z"
Creating a new appointment with the ASP.Net RadScheduler gives me a RecurrenceRule of, "DTSTART:20120830T110000Z
When I attempt to use the WinForms rule in the ASP.Net RadScheduler I get a single appointment with no recurring appointments.
When I attempt to use the ASP.Net rule in my WinForms Application, the program crashes before the form finishes loading.
I am using both the WinForms and the ASP.Net RadSchedulers. Please let me know what I can do to continue to use both.
