Hi Karl Wilkens,
In the pasted code I can not see the INTERVAL :
Start 2010-07-06 07:00:00.000
End 2010-07-06 08:00:00.000
RecurrenceRule DTSTART:20100706T070000Z DTEND:20100706T080000Z RRULE:FREQ=WEEKLY;UNTIL=20110701T000000Z;INTERVAL=
Also please note that "this is a built-in limitation of the JSON serializer. The JSON serializer implicitly requires its serialization targets to not contain infinite object graphs. For example the JSON serializer cannot serialize an array containing an entry that is a reference back to itself. In the reported case the JSON serializer is encountering a property somewhere on the DataView that eventually causes the JSON serializer to attempt to serialize the DataView all over again.
Take a look at this forum post
of Microsoft for the same error.
Could you please open new Support thread and send me your project so I can inspect it and help you?
