Linq to Sql gives you the ability to read data as well as Insert Update and Delete.
I looked through the source code unit tests and the docs, I only see mention of using Linq to LLBLGen to Fetch entity and entity collection data. I see no mention of how / if Linq to LLBLGen supports update, delete, insert.
Since I am using adapter, is it safe to assume that after I use Linq to fecth some entities/entity collections, that I should commit changes to those entities/entity collections using the standard adapter.DoXyzOnEntity or adapter.DoXyzOnEntityCollection methods?
