The DataService(Of T) class does the basic integration of all components of the server system. A new data service that uses system defaults for authorization and caching is created by defining a class that derives from the DataService(Of T) class and by referencing a compatible data model.

The type of the DataService(Of T) must expose at least one property that returns an entity set that is an IQueryable(Of T) collection of entity types. This class must also implement the IUpdatable interface to enable updates to be made to entity resources.
