Nullreferenceexception when adding a GData.Extensions.Reminder to Reminders

Question

Hello again, I think the title says it all. I'm using

Reminder fifteenMinReminder = new Reminder();
fifteenMinReminder.Minutes = 15;
fifteenMinReminder.Method = Reminder.ReminderMethod.email;
entry.Reminders.Add(fifteenMinReminder);

on a brand new entry (where Reminder and Reminders are Nothing), but I cannot add a reminder using the above code (taken straight from the Google Docs), or set the entry.Reminder to fifteenMinReminder directly either.

What am I doing wrong? I've had no trouble .adding When and Where's to the entry, but the Reminder doesn't want to follow the same pattern.

Any ideas?

After comparing the PHP docs with the .NET docs, I finally found out that the Google .NET API docs are wrong. You need to add the Reminder to the EventEntry.Times property:

Dim eventTimes As New [When]()

// Add StartTime and EndTime etc'

Dim fifteenMinReminder As New Google.GData.Extensions.Reminder()
fifteenMinReminder.Minutes = 15
fifteenMinReminder.Method = Reminder.ReminderMethod.alert //.all doesn't work for me 
eventTimes.Reminders.Add(fifteenMinReminder)
entry.Times.Add(eventTimes)

Unfortunately, this only works for single events because recurring events do not have a Times property (well you can set one, but it doesn't have any effect) - which brings me to my next stackoverflow question...
