Correct, the Calendar API v2 is deprecated and you need to update to v3, which 
is supported by another set of libraries:

Hi again.

unfortunately, i am unable to connect to my customer's gmail calendar any more 
using the old way, my program is a windows service.

i used your old calendar api 2.2, it was working with google calendar .net 
library using c#.

i used your api's method that called setUserCredential in order to connect, but 
its useless now.

i understand that my only way making it work is to use oAuth2, but how can i 
use it with installed windows service, tried the stream example, it works fine 
with stand alone app, but not on windows service.

this windows service can be installed on a remote server that holds more than 1 
google user, this service will sync our application sql data with these user's 
Calendar on google.

please assist, is there any example, our customers are out of service since 
17/11/2014?
