Entity Framework and LINQ to SQL

1/16: Updated with corrections from Readers. I’d hoped to completely avoid any discussion surrounding the future (or futures) of Entity Framework and Linq2Sql. And yet, my LINQ talks at CodeMash got hijacked with questions about these two libraries...

Extension Methods and Null Arguments
