LINQ2SQL: Where is the DataShape class?

We’re going to use LINQ2SQL in a project. Don’t ask why we’re not doing Entity Framework. When you start out with LINQ2SQL, you’ll google bing on “LINQ2SQL”. This, if you feel lucky, ends up in this page:

The page is long and old. The read, you’ll just have to cope with. That it is old is sometimes annoying because it’s outdated. What I couldn’t really find was the DataShape class on msdn. That’s because it’s now called the DataLoadOptions class. The DataShape class comes from the beta version of LINQ2SQL.

Hope this helps out other people searching for the DataShape class.
