Some of the key-benefits of Linq are:

- Unified querying of Objects, Database and XML eases the interaction between XML and databases.
- High performance
- Lesser time to code resulting in faster & improved productivity of developers.
- Ease of switching from Disconnected/Offline mode to Online mode in Smart Client applications.

Most Smart Client applications use XML as datasource in Offline mode & use SQL database in the Online mode. Since only the datasource name changes and other code remains AS-IS, it becomes easier to handle data.

Prerequisite for usage of sample application:
- AdventureWorksDb Database (SQL Server 2005)
