使用Xamarin.Controls.SignaturePad.Forms时，UWP应用程序在发布模式下崩溃

Question

我正在使用 Xamarin.Controls.SignaturePad.Forms 进行签名。以下代码在我调试时工作得很好。但是应用程序在发布版本中崩溃了。 当我从属性中恢复点时，应用程序崩溃。

public partial class MainPage : ContentPage
    {

        public IEnumerable<Point> Points { get; private set; }

        private SignaturePadView sigview;

        public MainPage()
        {
            InitializeComponent();

            var x = new StackLayout();


             sigview = new SignaturePadView()
            {
                HeightRequest = 320,
                WidthRequest = 240,
                BackgroundColor = Color.White,
                CaptionText = "Caption this",
                CaptionTextColor = Color.Black,
                ClearText = "Clear!",
                ClearTextColor = Color.Black,
                SignatureLineColor = Color.Black,
                StrokeColor = Color.Black,
                StrokeWidth = 2
            };

            var btn1 = new Button(){ Text = "save"};
            var btn2 = new Button(){Text = "Restore"};

            btn1.Clicked += Btn1_Clicked;
            btn2.Clicked += Btn2_Clicked;

           x.Children.Add(sigview);
           x.Children.Add(btn1);
           x.Children.Add(btn2);

            this.Content = x;

        }

        private void Btn2_Clicked(object sender, EventArgs e)
        {

                this.sigview.Clear();


                this.sigview.Points = this.Points;


        }

        private void Btn1_Clicked(object sender, EventArgs e)
        {
            this.Points = this.sigview.Points;
        }
    }

例外记录
