During the first half of 2007, trainers from Microsoft, Sonata, InfoSupport, Allette, Predeek Consulting and others delivered Open XML developer workshops in over 30 countries. These workshops were all structured around a set of inter-related presentations and hands-on labs that cover typical Open XML development scenarios.
Those presentations and hands-on labs (as well as all supporting content, such as demo files) are now available for free download from OpenXMLDeveloper.org at the links below.
These files have been updated for the Open XML SDK 2.0.
