  UserCredential credential;

            var initializer = new GoogleAuthorizationCodeFlow.Initializer
            {
                ClientSecrets = secrets,
                Scopes = new[] { PlusService.Scope.PlusLogin }                
            };
            var flow = new AAGoogleAuthorizationCodeFlow(initializer);
            credential = await new AuthorizationCodeInstalledApp(flow, new LocalServerCodeReceiver()).AuthorizeAsync
                ("user", CancellationToken.None).ConfigureAwait(false);

            // Create the service.
            var service = new PlusService(new BaseClientService.Initializer()
            {
                HttpClientInitializer = credential,
                ApplicationName = "Gus API",
            });
