In October 2008 I summarised LINQ to SQL vs LINQ to Entities as:

  • If you only care about SQL Server AND you have complete control of the “shape” of the db schema AND the application will live at most a few years, then LINQ to SQL is a good choice. LINQ to Entities would also work.
  • If you have virtually no control of the “shape” of the db schema OR you are working against a RDBMS other than SQL Server OR you are building an application that will live many years, then LINQ to Entities is the best choice

In Jan 2008 Elisa published a document on “LINQ to Relational” covering both technologies which contained the following two tables.
