These are the slides for the short version of my talk, presentation time for those is approx. 30 minutes. A slide set which goes into more detail for the DLR and .NET dynamic features is geared for 90 minute talks incl. demos. -- The slideshare viewer neither features the animations nor all correct fonts of my original PowerPoint 2010 presentation. That's the reason why some of the typography and alignment looks funny/weird. Most slides in the original file are animated so that the audience doesn't get overwhelmed by text and information.
