Exiv2 in 64-bit (or another EXIF writer)

Question

I need a non-destructive way of adding EXIF tags to jpeg images from .NET code. So far I have found Exiv2 and the .NET wrapper Exiv2net that works well when adding or updating tags. However, my code needs to run on a 64-bit machine (and compiled for 64-bit due to other reasons) and it seems to me that the Exiv2 code only compiles in 32-bit.

I am therefore looking for either someone working on a 64-bit version of Exiv2 and Exiv2net or another toolkit entirely. Has anyone seen such a thing?

Btw, the BitmapMetadata from WPF removes EXIF tags when updating and will not work for my purposes.

If you know your target system will have a Perl interpreter, you could bundle exiftool and call it to do work on behalf of your app. You may even be able to compile it into a standalone executable.
