I have an instance of a System.Drawing.Bitmap and would like to make it available to my WPF app in the form of a System.Windows.Media.Imaging.BitmapImage<
System.Drawing.Bitmap
System.Windows.Media.Imaging.BitmapImage<
The easiest thing is if you can make the WPF bitmap from a file directly.
Otherwise you will have to use System.Windows.Interop.Imaging.CreateBitmapSourceFromHBitmap.
