ADO.NET vNext Part 2: Using the Object Services Layer

Overview The first installment of the three-part article series introduced the core concepts of ADO.NET vNext, including the Entity Data Model (EDM), Entity SQL, and the Mapping Provider. It also discussed the steps involved in executing entity SQL queries against the EDM and retrieving output in the form of rows and values (contained in a DbDataReader object). This installment builds on Part 1, focusing on a layer named the Object Services Layer that lets a person work with database tables and columns as objects, and properties. The object services layer is an abstraction on top of EDM that leverages the same EDM infrastructure to execute queries against a database.
