Set System.Drawing.Icon as Source for ImageIcon control - WinUI 3

Question

Hi I am using C# WinUI 3 WinAppSDK for my app.

I have a list of files from my desktop folder for example.
A few are image files which have thumbnails in Windows File Explorer.
I want to have the same thumbnails in my app's ImageIcon or Image element.
I extracted the icon from the files:

      Icon iconn = System.Drawing.Icon.ExtractAssociatedIcon(file.Name);  

Now I want to set this icon for the ImageIcon control. Please tell how

You can use GetThumbnailAsync instead.
Test with Notepad :

            var file = await Windows.Storage.StorageFile.GetFileFromPathAsync(@"c:\windows\system32\notepad.exe");  
            var iconThumbnail = await file.GetThumbnailAsync(ThumbnailMode.SingleItem, 32);  
            var bi = new BitmapImage();  
            bi.SetSource(iconThumbnail);  
            imgIcon1.Source = bi;
