Can you post the service contract in your assembly, and the accompanying config file? Can you also post the command line used to invoke WcfSvcHost? I don't guess you've used that in VS2005 to debug (since it was only released with VS2008) - maybe there's something wrong there.
At first glance, it looks like the service type referenced in the config file probably isn't available in the service assembly.
