I just posted a new release for SilverlightDatabase project on CodePlex : http://silverdb.codeplex.com/

There was an issue with the latest release - you could potentially get an error when adding data to a table previously saved.  I posted a bug fix release for this that also includes unit test to verify that the issue is resolved.

Please download this release if you are using this project.

Thank you.
