Any sharpziplib commercial support?

Govt client doesn't like open source. Legacy app used sharpziplib without getting permission. They'll pay for support, so we don't have to rewrite (your tax dollars at work), but I can't开发者_如何学编程 find anyone who provides paid support for sharpziplib.

Any ideas?

It is a GPL project that is fully open source, so paid support is not going to be easily available.

Why can't you buy a commercial zip component and pay for it and support? There are plenty of those around.
