Above is the ics for new event created on iCloud. I came across with a problem while fetching events from iCloud. Problem is that the event that are directly created on iCloud are not getting parsed using ical.net. While that are being parsed by dday.ical. Event created using ical.net are parsed correctly. Above ics is parsed correctly by DDay.iCal.

Using ical.net
MemoryStream stream = new MemoryStream(Encoding.UTF8.GetBytes(ics))
IICalendarCollection calendars = Calendar.LoadFromStream(stream, Encoding.UTF8);

Error comes at Calendar.LoadFromStream and error is String was not recognized as a valid DateTime.

Using Dday.iCal
MemoryStream stream = new MemoryStream(Encoding.UTF8.GetBytes(ics))
IICalendarCollection calendars = iCalendar.LoadFromStream(stream, Encoding.UTF8);

Above code of Dday works fine for same ics.

Problem this with VTIMEZONE component which is not getting parsed by ical.net. When we create request for get all meetings we ask for properties of event we want in response. If not needed then remove timezone component from request i.e don't ask for timezone component. Remove from your request. Thanks

When I saw this I was using version 2.2.30 which was latest at that time. This problem is solved in version 2.2.31 and fix will be available for higher version as well. See release note for version 2.2.31 : https://github.com/rianjs/ical.net/blob/master/release-notes.md

I have checked this on latest for now i.e 2.2.33 and it is working fine now.
