Hi, I see tool like SN which generates private/public key pair for signing an assembly. and using AL tool we can assign a strong name to an assembly And we have also Sign tool which is used for signing the assembly (probably for using with certificates exclusively?). What is the exact difference between the two?. Is it sign tool have to be used when working with certificates and can it we acheive it SN?. or are they totally different.? Please help.
