Hi

This is a question for all those .Net gurus who have ssen umpteen .Net
products come and go so far. The question is fairly simple -- Do the
softeware houses really obtain digital signatures from (eg. Verisign) and
sign their assemblies before releasing them for production? How important it
is to sign the assemblies (with digital signature obtained from Verisign or
otherwise) before it is installed on the client machine? More so, if the
product is supposed to be a stand alone product which very rarely accesses a
networked resource like a configuration file?

Regards

Rahul
