I once had to use a utility called iwsq to extract bitmap from a wsq file. Unfortunately, it was binary only, the source was unknown, and there was no source code.

Searching for iwsq brought up this archive that you'd call as executable directly from c#.

There is also the FFPIS project on SourceForge. It has not been updated since 2004, but the links may provide more code.

WSQ Image Library is a WSQ-related SDK that comes with a price tag.

NIST also provides some download material and source code.
