How to convert Mat to bitmap in C# using EmguCV?

I'm trying to convert Mat to bitmap to open my webcam but with no success. However, I've seen a question with the same context compared to this question but without any answer from the other users : question ,

This is the code used :

  private void OpenWebcam_Click(object sender, RoutedEventArgs e)
    
    {
        var capture = new Emgu.CV.VideoCapture();

        using (var nextFrame = capture.QueryFrame()) 
        {
            if (nextFrame != null)
            {
                image.Source = nextFrame.ToBitmap(); // error here because there is no ToBitmap method
            }
        }

    }

Note that the code I've found in this question How to get video stream from webcam in emgu cv? seems to have worked, but I'm using a new version so the method was deleted.

If using WPF, you can install Emgu.CV.Wpf then connect the output to a System.Windows.Controls.Image object.

    // Convert the Mat to a BitmapSource for display in WPF
    image.Source = nextFrame.ToBitmapSource();

I've solved this problem after installing : Emgu.UI.windows and now , this code works for me:

 var bitmap = Emgu.CV.BitmapExtension.ToBitmap(nextFrame);
