PDC 2004 was really a succesful event. Almost all the speakers were great specially Rafal Lukawiecki,Clemens Vasters,Gosking Baker and Farhan Muhammad impressed me the most (and I guess the whole crowd). I really enjoyed sessions on SOA, Threat Modeling,ADO.Net best practices, Web Application Security,Indigo, and MSF.
During PDC I got to learn a lot about SOA, Threat Modeling. And Microsoft Solutions Framework is something that has found my interest.
