use valid email address. It will work

    UserCredential credential;
   using (var stream = new FileStream("client_secrets.json", FileMode.Open,   FileAccess.Read))
    {
        credential = GoogleWebAuthorizationBroker.AuthorizeAsync(
            GoogleClientSecrets.Load(stream).Secrets,
            new[] { TasksService.Scope.Tasks },
            "shyam.sundar@gmail.com", CancellationToken.None, new FileDataStore("Tasks.Auth.Store")).Result;
    }            
   //credential=new UserCredential(
    // Create the service.
    var service = new TasksService(new BaseClientService.Initializer()
    {
        HttpClientInitializer = credential,
        ApplicationName = "Tasks API Sample",
    }); 
 ListTaskLists(service)
