How do i decode/open raw image files like .CR2 or .NEF and .ARW without having the codec installed, something like lightroom open raw files ? My code look like this:
If you insist on not installing a codec, then your best bet might be these:

http://sourceforge.net/projects/dcrawnet/ - apparently a (partial?) port of DCRAW to C#, but project does not seem to be active
