The Data Access Guidance Package will be removed from the Web Service Software Factory in v3.0 and be a separate guidance package.
It has a new home on CodePlex and is called the Repository Factory. Per the website:
"The Repository Factory is a guidance package that automates creation of entity classes that map to database tables and repository classes to read and write those entity classes. The generated code removes the tedium of writing a persistence-ignorant domain model.
This package was originally published as the "Data Access Guidance Package" as part of the Web Service Software Factory. Data access is a much larger problem space than just services, so we've decided to split this package out into its own project."
