そこで、Visual Studio 2012 at School で完璧に動作するこのプログラムを作成しようとしています。

しかし、私が家にいるとき、このThrown ExceptionエラーがPublic Game1().

プログラムを実際に実行して終了できるように、誰かがこれを手伝ってくれることを願っています。

コール スタックは次のとおりです。

System.NullReferenceException: オブジェクト参照が Microsoft.Xna.Framework.OpenTKGameWindow.Initialize () [0x00000] のオブジェクトのインスタンスに設定されていません。 0 at Microsoft.Xna.Framework.OpenTKGamePlatform..ctor (Microsoft.Xna.Framework.Game game) [0x00000] in :0 at Microsoft.Xna.Framework.GamePlatform.Create (Microsoft.Xna.Framework.Game game) [0x00000] ] in :0 at Microsoft.Xna.Framework.Game..ctor () [0x00000] in :0 at MonoGameTest.Game1..ctor () [0x00023] in /Users/sebnabt/Projects/MonoGameTest/MonoGameTest/Game1.cs :38 at MonoGameTest.Program.Main () [0x00001] in /Users/sebnabt/Projects/MonoGameTest/MonoGameTest/Program.cs:19

Xamarin Studio でビルドしていますか? 数日前の質問で説明したのと同じ問題が発生していると思います。そこで私の答えを見てください：https://stackoverflow.com/a/18798311/793449

要約すると、Xamarin Studio は、mac アセンブリではなく WindowsGL フレームワーク アセンブリを選択しています。最新のソース (MonoGame.Framework.MacOS プロジェクト) から MonoGame を自分でビルドし、ゲーム内の参照を変更する必要があります。
