AlternateUri returns null pointer exception when used on CalendarEntry instances

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Fetch http://www.google.com/calendar/feeds/default/owncalendars/full
2. For one of the CalendarEntry instances that's returned, attempt to
access it's AlternateUri property.

(See attached sample code.)

What is the expected output? What do you see instead?
The Calendar's event feed URL should be returned. Instead, a null pointer
exception results.

Please provide any additional information below.
The problem here seems to be that AlternateUri expects to see an link with
rel="alternate" and type="text/html".

As a workaround, users can use the following instead:

calendarEntry.Links.FindService("alternate", "application/atom+xml")

Trevor, 

you are getting a null pointer exception because you are accessing 
AlternateUri.Content. And if alternate URI is 
null, that crashes. 

The defintion of alternateUri property states that it is using alternate & 
text/html. If you want something else you 
use the above method. It is a shortcut to access alternate & text/html, not a 
shortcut to access the first random 
alternate.
