My class uses an image as Property (public Image myImage). When this class is serialized (XamlWriter) it works fine, reading it back gives an exception:

'No matching constructor found on type 'System.Drawing.Bitmap'. You can use the Arguments or FactoryMethod directives to construct this type.' Line number '5' and line position '8'.

Obviously there is a constructor missing for Bitmap with ColorPalette as argument:

<sd:Bitmap>
  <sd:Bitmap.Palette>
    <sdi:ColorPalette /> 
  </sd:Bitmap.Palette>
</sd:Bitmap>

I understand that I can specify a factory method creating the bitmap somehow. I also found some articles about directives for this such as http://www.wpftutorial.net/XAML2009.html

However, I am not an expert in Xaml and do not understand how and where to define / declare the method on my attribute. Unfortunately i do also not find an example for this.

I expect some like 

[FactoryMethod("XYZ")]
public Image myImage ....

but actually have found nothing. Any idea / example you know?
