        UserCredential credential = GoogleWebAuthorizationBroker.AuthorizeAsync(
                        new ClientSecrets
                        {

                        new[] { CalendarService.Scope.Calendar },"user",CancellationToken.None).Result;

        // Create the service.
        var service = new CalendarService(new BaseClientService.Initializer()
        {
            HttpClientInitializer = credential,
            ApplicationName = "Calendar API Sample",
        });

        {
            Summary = "Appointment",
            Location = "Somewhere",
            Start = new EventDateTime()
            {
                DateTime = new DateTime(2014, 6, 2, 10, 0, 0),
                TimeZone = "America/Los_Angeles"
            },
            End = new EventDateTime()
            {
                DateTime = new DateTime(2014, 6, 2, 10, 30, 0),

            },
            Recurrence = new String[] { "RRULE:FREQ=WEEKLY;BYDAY=MO" },Attendees = new List<EventAttendee>(){new EventAttendee() { Email = email } }
        };

        Event recurringEvent = service.Events.Insert(myEvent, "primary").Execute();

I have resolved issue my self.Problem was I have put type as "Web Application" Instead of "other".. After I changed it to type as "other" It worked.
