Part 1:
In the past, working with data has required learning a number of different API sets for each kind of data you needed to access. Relational data requires ADO. XML uses Xpath, XQuery and the XML Dom. Objects require you to write your own manipulation code. In this video, Jim Wooley (MVP in VB) introduces the Language INtegrated Query (LINQ) project and demonstrates how to leverage it to use a single API to work against objects or relational data. In it, we explore extending an existing web site to add the ability to load a set of web links from a database and display them using ASP.Net with Visual Studio code name "Orcas". He starts with a standard object collection populated by a DataReader and demonstrates how to eliminate the plumbing code using LINQ and LINQ to SQL.
