This Wrox Blox introduces you to Language Integrated Query (LINQ), a .NET 3.5 application programming interface (API) and set of extensions to the Visual Basic and C# languages. First, you get acquainted with LINQ¿s Standard Query Operators (SQOs) and new keywords that define the language. Then you use the SQOs to write LINQ expressions in C# 3.0 and VB 9.0 that let you query diverse data types with a single syntax that¿s similar to Structured Query Language (SQL). You also discover how to take advantage of a shorthand method-call syntax that chains lambda expressions. Next you discover how Visual Studio 2008¿s primary domain-specific LINQ implementation¿LINQ to SQL¿persists collections of business objects in SQL Server 200x Tables. You dig into the details of creating an object-oriented data access layer (DAL) with LINQ to SQL¿s graphical object/relational mapping (O/RM) tool. You see how to automatically generate entity classes by dragging table nodes from a Server Explorer connection to the O/R Mapper¿s and discover how associations between entities called EntityRefs and EntitySets correspond to n:1 and 1:n relationships. You also learn how to use the DAL to bind UI controls on data-driven Web pages with ASP.NET¿s new LinqDataSource control that substitutes for the ObjectDataSource control. Complete C# 3.0 and Visual Basic 9.0 project code for the LINQ2SQL2ASP.sln project is available for downloading.
