You can use the following configuration to specify the namespace, contract name, and user defined types to be included. You can also specify other settings for a service contract

  <comContract contract="{5163B1E7-F0CF-4B6A-9A02-4AB654F34284}"
    name="_Broker" namespace=""
      <add exposedMethod="BuyStock" />
