I have reviewed the documentation and it basically says to drop the nsoftware dll into the bin of commercemanager and then you can see it in the admin tool. I did that and the class name dropdown is empty. All of the documentation assumes that the dropdown will be filled so I am at a stuck point until I can get that dropdown to fill. I looked at the source code and it appears to be scanning the dlls in the bin, looking for anything that implements the gateway interface. I would assume that the nsoftware classes implement the interface.
Any ideas?
