Attempting to connect to Calendar/Event Service 401 Invalid Credentials error

[GoogleCodeExporter]

I am using the latest version of the API (1.2.4647.29713) and am unable to 
access any of the information due to an error 

Google.GoogleApiRequestException was unhandled

This is occurring for codesample,

 var auth = new OAuth2LeggedAuthenticator(Constants.ClientId, Constants.ClientSecret, user.Replace(string.Format("@{0}", Constants.ClientDomain), ""), Constants.ClientDomain);

                var service = new Google.Apis.Calendar.v3.CalendarService(auth);
                var bookings = service.CalendarList.List().Fetch().Items.Where(p => p.Summary == Constants.CalendarName).FirstOrDefault();

This code DID work as of version (1.1.4344.232403) which i was going to attempt 
to go ahead and use, but am now getting an error code of 400 when attempting to 
submit an event.

Is there a fix pending for this issue, or perhaps a recommended alternate 
method of Authentication to use?

I belive there has been some changes to authentication at the server end. I 
would try following the code in the samples, either for asp.net 
http://code.google.com/p/google-api-dotnet-client/source/browse/Tasks.ASP.NET.Si
mpleOAuth2/Default.aspx.cs?repo=samples#72

Or for a native application: 
http://code.google.com/p/google-api-dotnet-client/source/browse/Tasks.CreateTask
s/Program.cs?repo=samples#47

Hope that helps.

Same issue for me, using version 1.2.4737.

It worked with version 1.1.4344. :

var auth = new OAuth2LeggedAuthenticator("ConsumerKey", "ConsumerSecret", 
"UserLogin", "Domain"); // userLogin does not contain '@domain'

var _service = new CalendarService(auth);
_service.Key = this.APIKey;  // created in API Console 

CalendarListResource.ListRequest request = _service.CalendarList.List();
CalendarList feed = request.Fetch();

throws:

Google.Apis.Requests.RequestError
Invalid Credentials [401]
Errors [
    Message[Invalid Credentials] Location[Authorization - header] Reason[authError] Domain[global]
]
