.NET NullReferenceException when adding Reminder to entry.Reminders

Name of API affected:
Calendar Data .NET API

Issue summary:
Provide a brief summary of the issue you're experiencing.

Problem: nullreference exception on adding Reminder to entry.Reminders

Workaround: Add to When, add When to entry.Times instead

Outcome: Workaround only works for single events.

Steps to reproduce issue:

1. Use the following code from the .NET API Docs to add a Reminder to 
any event, recurring or single:

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

Expected output:

Reminder added to EventEntry

Actual results:

NullReferenceException on entry.Reminders.Add(fifteenMinReminder);

Notes:

This happens despite the affirmation by Austin (Google) on 
http://groups.google.com/group/google-calendar-help-
dataapi/browse_thread/thread/bc98afb472fe3014/f36ac2356b85b41b?
lnk=gst&q=Re:+Alarms+on+recurring+events+via+protocol%3F#f36ac23
56b85b41b 

that:

 You can insert reminder to a recurring event with a 
<gd:reminder>element directly to the <entry> element, since there is no 
<gd:when> element (which is the normal place where reminder typically 
goes for single event).

To test I added a reminder directly under the gd:recurrence for recurring 
events in the XML and this does indeed work fine, so I presume this is a 
bug in the .NET API?

I tried adding a Reminder with the posted code to both single and recurring 
events and it worked without exception.

Marking this issue as Invalid.

Are you using the latest version of the client library?

I have the same error with same code too.
I use the latest version (1.8) of the Google.GData.Calendar.dll.

Maybe the When must be before? If i change the order (it should be then first 
When, and after then Reminder), then it is all right. Or it can be the line 
"entry.Notifications = true;" too; Now is that line also before the adding the 
reminders to entry.

Sorry, i'm late actually, but as i wrote, it's all right by me now. I think, it 
was the order, but i can't tell wich line was it exactly. Now my order:
0. Setting the reminders.
1. Setting up "When".
2. Adding "When" to event.
2. Switch notification on.
3. Adding reminders to event.
Now works like a charm.
