The biggest change in .NET Framework V3.5 and Visual Studio 2008 was the introduction of Language Integrated Query (LINQ). In this session we’ll talk about what LINQ is, how it works and how it can be extended to any data source via the IEnumerable and IQueryable interfaces. We’ll look in brief at the implementations that come in .NET Framework V3.5 (LINQ to Objects, LINQ to XML, LINQ to SQL) and take a glance at the implementation coming in ADO.NET Entity Framework.
