Something to know to get DLINQ working
I had a little issue with running through the DLINQ sample on SQL Server 2005. The sample uses auto-attaching of databases, which didn't work on my box.
Solve this by attaching the database from "C:\Program Files\LINQ Preview\Data\northwnd.mdf" using the SQL Server Management Console and replace this line
DataContext db = new DataContext(
@"C:\Program Files\LINQ Preview\Data\northwnd.mdf");
with this line
DataContext db = new DataContext(
@"Data Source=localhost;Initial Catalog=Northwind;Integrated Security=True");
