Detailed Description

Provides an automated way to reuse LINQ data context objects within the context of a single data portal operation.

Template Parameters

C	Type of database LINQ data context objects object to use.

This type stores the LINQ data context object in Csla.ApplicationContext.LocalContext and uses reference counting through IDisposable to keep the data context object open for reuse by child objects, and to automatically dispose the object when the last consumer has called Dispose."
