LINQ to Entities

I recently received an email asking about LINQ to Entities.  Earlier in the developmental stage of LINQ and my book, it became clear that LINQ to Entities was outside the umbrella of core LINQ.  The fact that it did not ship with VS 2008 is a primary indicator of this fact.  In truth, despite being announced quite some time ago, LINQ to Entities appears to be the redheaded stepchild of LINQ.  However, now seems as good a time as any to start providing more information about LINQ to Entities.

What is LINQ to Entites?

LINQ to Entities is the name used to refer to querying the ADO.NET Entity Framework with LINQ.
