This sample shows you how to use LINQ to SQL to store relational data in a local database that resides in your app’s storage container.
In Windows Phone OS 7.1, you can use LINQ to SQL to store relational data in a local database that resides in your app’s isolated storage container. This sample is a to-do list app that uses a multi-table local database. Items that appear in the list are added, updated, and deleted from a local database, where they persist between app launches. For info about how to develop this app step-by-step, see How to create a local database app with MVVM for Windows Phone.
You need to install Windows Phone SDK 7.1 to run this sample. To get started, go to the Windows Phone Dev Center.

When the app launches for the first time, no to-do items appear in the list. Isolated storage is not persisted between launches of Windows Phone Emulator. Run the app on a Windows Phone OS 7.1 device to observe data being stored in the database between app launches. |
