Exception in CanvasGeometry.CreatePolygon while mouse drag on canvas in WinUI

[powerpdw]

Hello.
I am using canvas geometry.
But in CanvasGeometry.CreatePolygon(), exception is being occured.
Because of these exceptions, rendering performance is too poor.
How can I avoid this problem?

Exceptions
Exception thrown at 0x7588B4B2 in App6.exe: Microsoft C++ exception: EEMessageException at memory location 0x027AD4C0.
Exception thrown: 'System.DllNotFoundException' in System.Private.CoreLib.dll
Exception thrown: 'System.IO.FileNotFoundException' in System.Private.CoreLib.dll

Below is the code to reproduce the exception.

MainWindow.xaml.cs

    public sealed partial class MainWindow : Window
    {
        private object _lockCanvas = new object();
        public MainWindow()
        {
            this.InitializeComponent();

            myCanvas.Draw += MyCanvas_Draw;
            myCanvas.PointerMoved += this.canvasChart_PointerMoved;
            myCanvas.PointerPressed += this.canvasChart_PointerPressed;
            myCanvas.PointerReleased += this.canvasChart_PointerReleased;
        }

        private void canvasChart_PointerMoved(object sender, PointerRoutedEventArgs e)
        {
            CanvasControl canvas = sender as CanvasControl;
            if (canvas == null)
            {
                return;
            }
            if (myCanvas.PointerCaptures != null && myCanvas.PointerCaptures.Count > 0)
            {
                canvas.Invalidate();           // repaint
            }
        }

        private void canvasChart_PointerPressed(object sender, PointerRoutedEventArgs e)
        {
            CanvasControl canvas = sender as CanvasControl;
            if (canvas == null)
            {
                return;
            }

            canvas.CapturePointer(e.Pointer);
        }

        private void canvasChart_PointerReleased(object sender, PointerRoutedEventArgs e)
        {
            //do something
            CanvasControl canvas = sender as CanvasControl;
            canvas.ReleasePointerCaptures();
        }

        private void myButton_Click(object sender, RoutedEventArgs e)
        {
            myCanvas.Invalidate();
            myButton.Content = "Clicked";
        }

        private void MyCanvas_Draw(Microsoft.Graphics.Canvas.UI.Xaml.CanvasControl sender, Microsoft.Graphics.Canvas.UI.Xaml.CanvasDrawEventArgs args)
        {
            if (sender.ReadyToDraw == false)
            {
                return;
            }
            CanvasGeometry canvasPolygon = CanvasGeometry.CreatePolygon(sender, new Vector2[] { new Vector2(0, 0), new Vector2(100f, 0f), new Vector2(50f, 100f) });
            args.DrawingSession.DrawGeometry(canvasPolygon, Colors.Blue);

        }
    }

Are you trying to run this with Win2D for WinUI3 or Win2D for UWP?

At least some of those exceptions are caused by activation not understanding where to find the classes you're working with. For each class that's giving you trouble (you can comment out code to narrow it down if necessary), put the following into your package.appxmanifest (Currently formatted for CanvasControl)

<Extension Category="windows.activatableClass.inProcessServer">
    <InProcessServer>
        <Path>Microsoft.Graphics.Canvas.dll</Path>
        <ActivatableClass ActivatableClassId="Microsoft.Graphics.Canvas.UI.Xaml.CanvasControl" ThreadingModel="both" />
    </InProcessServer>
</Extension>

I've putted the xml code in package.appxmanifest.
But error was occured.
"Manifest references file 'Microsoft.Graphics.Canvas.dll' which is not part of the payload."

This is the code of Package.appmanifest.
