Creating LINQ to SQL Entities
LINQ to SQL enables you to perform LINQ queries against database data. Currently, you can use LINQ to SQL with Microsoft SQL Server 2000, Microsoft SQL Server 2005, or Microsoft SQL Server 2008 (including the SQL Server Express editions). Other databases—such as Oracle, DB2, and Access databases—might be supported in the future, but they are not right now.
Note
To use LINQ to SQL, you need to add a reference to the System.Data.Linq.dll assembly. Select Website, Add Reference and, beneath the .NET tab, select System.Data.Linq. Performing this action adds a new assembly reference to the <assemblies> section of your web.config file. If you use the LINQ to SQL Designer, this reference is added automatically.
