If you are using the Web Service Software Factory from Microsoft Patterns & Practices and looking to integrate it with the Enterprise Library Policy Injection Application Block, you may want to check out the Web Service Software Factory Contrib Project.
Per the Web Service Software Factory Contrib Project:
"The EntLib 4.0 Policy Extensions: The goal of these extensions is to simplify the task of integrating PIAB (Policy Injection Application Block) and WCF by providing some features like, design time support for applying policies to services, generating a host config with all the required sections that points to the specified entlib config file and implementing a WCF behavior that abstracts you from wrapping or creating objects using the PIAB factory."
You can download the Enterprise Library 4.0 Policy Extensions here.
