Answer 17

You should run Sn.exe. The Strong Name tool creates a strong name for an assembly, which is required for the assembly to be placed in the GAC. A strong name is a unique name for an assembly. It consists of the assembly name, version, culture, public key, and digital signature.
You should not run Regasm.exe. The Assembly Registration tool registers the assembly as a COM object. This does not prepare an assembly for being placed in the GAC.
You should not run Regsvr32.exe. The Component Registration tool allows you to register an assembly to be used by COM clients. This does not prepare an assembly for being placed in the GAC.
You should not run Ildasm.exe. The MSIL Disassembly tool allows you to access the intermediate language of an assembly. This does not prepare an assembly for being placed in the GAC.
