After canceling the event in 2004, Microsoft is planning to move forward with its Professional Developers Conference in 2005, according to Microsoft Watch. The conference will take place the week of September 11 in Los Angeles, California. While the PDC is traditionally developer-oriented with a multitude of learning sessions, the 2003 event sparked huge interest with the first official unveiling of Longhorn. And with Longhorn Beta 1 slated for next year, PDC 2005 will also likely be one to watch.
