There are some great VSTO community activities going on in Vienna.  Office Community Day is being held on May 8th in Vienna and is free.  They will be covering:

  • Introduction to VSTO
  • OpenXML
  • Deployment in VSTO
  • SharePoint Workflows

and more.  Mario Meir-Huber and Lars Keller are driving this, and having spoken before with Mario, he knows his VSTO!  The information page for the event is at http://www.vsto-taskforce.de
