Answer 1

The DBML file represents the data model for a LINQ to SQL project – it’s used to generate the C# code for the various entities.

The code you’ve provided is a LINQ query. I’d certainly expect to see LINQ queries within an application which uses a DBML file, but they are slightly separate. In particular, I wouldn’t expect to see queries either within the DBML file itself or in the C# code generated from it. The queries will be in the code which uses those entities.
