I am building an application to migrate from Google Apps Calendar to Outlook Web app Calendar. I can retrieve Calendar events from Google Apps using Google Calendar Api v3 except the Recurring events. I am getting the recurrence field as strings defining an RRULE, EXRULE, RDATE or EXDATE rule as defined by the RFC 2445. 

"RRULE:FREQ=WEEKLY;UNTIL=20110701T160000Z".

How to parse such Recurrence rules into various EWS managed Api Recurrence functions and patterns ?

Is there a third party library which can help me in this regard ? Or EWS managed api has a built-in functionality to parse such Rules?
