Want to find out more about LinQ (.Net Language Integrated Query)? We’ve been given
a white paper here at PDC, but there’s an online copy on MSDN here.
I think my favourite feature is the ability to articulate queries that span different
data sources, so, for example, collating information across WMI, AD and SQL simultaneously
becomes a trivial task!
