Windows Phone 7.1 - Local SQL Database

In the upcoming release of Windows Phone 7.1, Microsoft decided to add a Local Database implementation that is targeted to business applications and is created on top of SQL Server CE. This new feature completes the storage solutions available for the phone, supporting scenario where you need a real relational database and is really easy to configure and use. It does not totally override other solutions. Sterling remains a good solution for many scenarios, but having a real relational store is almost wonderful in many cases.
