Thank you guys for the help!. I cant help but note that MicroSoft did not develop a way to reliably verify that a particular person made a particular program , and that no one else is able to spoof or tamer the product or even be able to see what it does easily.

From the link, I saw that any one can extract the code and resign it with their key after modification. What I wished to see is a way to stop people from temering my assemblies, and at the same time not being able to know what it does.

For the time being, I will just sign my assemblies and keep my private key private, and pray no one tampers with my code.Sad
