When registering .NET assemblies for COM Interop, I do two things, currently in this order:
regasm /tlb:MyDll.tlb Mydll.dll
gacutil /i Mydll.dll
I use regasm
to register the type library for COM and gacutil
to install the assembly into the GAC. Does it matter which order I do these two actions? Also, as I make updates to my dll, do I need to un-register and re-register it, uninstall it from the gac and re-install it, both or neither?
