Read and write EXIF data with Silverlight

Question

I'd like to find a way to read AND write exif data of an image with Silverlight.

I couldn't find any sample code or library doing this, so I don't know if it's even possible?

Thanks

Update : I need to write (edit or add if necessary) exif data and more precisely the "Software" tag.

Answer 1

At work we use this, in a WPF Application so it might help

Answer 2

This is how you would read in SL: Understanding and Reading Exif Data. As the author is using FileInfo for this, the concept of reading can likely be reversed for writing (TIFF - Little Endian).
