The steps to register a dot net component is:


The command line instruction to create a strong name.

sn -k ComInterOp.snk.
Strong name is a unique name created by hashing a 128-bit 
encryption key against the name of the Assembly (ComInterOp 
in our case). The strong name is created using SN.exe, that 
would create ComInterOp.snk file, which we would use while 
creating the DotNet Assembly.

The command line instruction to create an assembly using 
the strong name 

vbc /out:ComInterOp.dll /t:library /keyfile:ComInterOp.snk

Assembly Registration Tool.

The Assembly Registration Tool (Regasm.exe), reads the 
metadata within an assembly and adds the necessary entries 
to the registry, which allows COM clients to create DotNet 
Framework classes transparently. The Assembly Registration 
tool can generate and register a type library when you 
apply the /tlb: option. COM clients require that type 
libraries be installed in the Windows registry. Without 
this option, Regasm.exe only registers the types in an 
assembly, not the type library. Registering the types in an 
assembly and registering the type library are distinct 
activities.
The command line instruction to create and register 
ComINterOp.tlb(Type Library) is

regasm ComInterOp.dll /tlb:ComInterOp.tlb.

The DotNet Services Installation Tool (Regsvcs.exe)

The command line instruction to install ComINterOp.dll in 
GAC is 

Gacutil -i ComInterOp.dll.
