I have released full source code of the News Framework on Oct 25, 2010. You can grab it from here (external).

Those who are unfamiliar with the News Framework here is a summary. News Framework is an open source (to be released in a while) offline news reading framework on which any RSS based news website can have its own Windows Phone 7 application in just minutes. The configuration, content and styles can be managed from outside of the framework itself to fit the needs.

Feature list of this framework can be found here (external).
