Well the PowerPoint slides that I used during the TechDays 2006 conference have been published in the TechDays page. You can download them from this site as well:
- A204 - SharePoint Workflow (zipped, 6.5 MB)
- D308 - LINQ (zipped, 6.7 MB)
BTW, they are in French… and yes, the slide with Maradona on it is maybe the most important of them all :))
