c# - Xamarin.Forms.Platform.UAP.dll で 'System.ArgumentException' が発生しました

Question

こんにちは、私は xamarin フォーム プロジェクトを作成し、MasterDetailPage を実装します。Android と ios の両方で問題なく動作していましたが、Windows 10 の UWP プロジェクトで例外がスローされ、アプリがクラッシュしました。私のスタックトレースを見つけてください

Xamarin.Forms.Platform.UAP.dll で 'System.ArgumentException' が発生しました
