How do I switch turns for each move?

How do I switch turns for each move?
I have written the following code.

GameInfo gi = new GameInfo() { Handicap = 0, StartingPlayer = Content.Black, Komi = 6.5 };
Game game = new Game(gi);

bool legal;
game.MakeMove(3, 3, out legal);
game.MakeMove(16, 16, out legal);

Debug.Log(game.SerializeToSGF(null));

What I get is this kind of SGF. It is a variation move of Black's first move and does not advance the number of moves.

(;SZ[19](;B[dd])(;B[qq]))

What I want is an SGF like this one.

(;SZ[19](;B[dd];W[qq]))

Hello, every MakeMove returns a new Game which represents the state after the move, so you need to do this:

GameInfo gi = new GameInfo() { Handicap = 0, StartingPlayer = Content.Black, Komi = 6.5 };
Game gameInitial = new Game(gi);
Game game = gameInitial;

bool legal;
game = game.MakeMove(3, 3, out legal);
game = game.MakeMove(16, 16, out legal);

Debug.Log(game.SerializeToSGF(null));

Thank you for reply!
However, no text was output.
It seemed to be caused by GameInfo being null.
So I fixed it as follows.

protected Game(Game fromGame) {
            Board = new Board(fromGame.Board);
            Turn = fromGame.Turn.Opposite();
            GameInfo = fromGame.GameInfo; // I added this line
            _captures[Content.White] = fromGame._captures[Content.White];
            _captures[Content.Black] = fromGame._captures[Content.Black];
            foreach (var p in fromGame._superKoSet) _superKoSet.Add(p);
            Root = fromGame.Root;
        }

With this fix, game properties such as Komi and size are now output, but Moves is stille not.
It seems that Game's _moves is empty when outputting, but I couldn't figure out how to fix it.

        private void SerializeToSGFInternal(TextWriter s) {
            if (_moves.Count == 1) { // I set a breakpoint here, but the Count was 0.
                var pnt = _moves.First().Move;
                SerializeMove(s, pnt);
                _moves.First().Game.SerializeToSGF(s);
            }
}
