As you might already have noticed, I'll be speaking at DevDays 2006.
I will be doing a talk on LINQ and the underlying features that have been added to C# 3.0 to make this programming paradigm possible. If you are interested on some info up-front, read the article I wrote during the PDC on this topic.
The full set of sessions can be found at http://www.microsoft.com/netherlands/msdn/devdays/overzichtsessies.aspx
See you there! (at 7th & 8th of March)
