Answer 1

//For google client.... 
using (var stream = new FileStream("client_secrets.json", FileMode.Open, FileAccess.Read)) 
     { 
      credential = await GoogleWebAuthorizationBroker.AuthorizeAsync(
       GoogleClientSecrets.Load(stream).Secrets, 
       new[] { BooksService.Scope.Books }, 
       "user", CancellationToken.None, new FileDataStore("Books.ListMyLibrary")); 
     } 

// Create the service. 
     var service = new BooksService(new BaseClientService.Initializer() 
      { 
       HttpClientInitializer = credential, 
       ApplicationName = "Books API Sample", 
      }); 
    var bookshelves = await service.Mylibrary.Bookshelves.List().ExecuteAsync(); 
     ... 
    } 

Thats the example of how you can create google client and service to make google authentication
