c# - What does GAC uses to keep record of DLLs -

i have utility class dll added gac of front end live server.

now need make copy of dll name , change little bit of code in it.

if copy renamed dll gac enough ? if both dlls generated different projects both projects has same guid or public key.

in short don't want gac mix renamed dll original dll

the gac uses assemblies strong-name identify it, combination of

simple text name, version number, , culture information (if provided) — plus public key , digital signature

given renaming dll gac should identify updated dll different assembly there should no issues overwriting the original.
