What is LINQ?

Enables the use of Language-Integrated Query (LINQ) in an ASP.NET Web page through markup text to retrieve and modify data from a data object.

• Language-Integrated Query (LINQ) is a query syntax that defines a set of query operators that enable traversal, filter, and projection operations to be expressed in a declarative way in any .NET-based programming language. The data object can be an in-memory data collection or an object that represents data from a database. You can retrieve or modify the data without having to write SQL commands for each operation.
• The LinqDataSource control enables you to use LINQ in an ASP.NET Web page by setting properties in markup text. The LinqDataSource control uses LINQ to SQL to automatically generate the data commands.
