Microsoft may be planning its Professional Developer’s Conference at home in Seattle.
The software giant held its PDC 2010 event at the Microsoft campus in Redmond last year. ZDNet’s Mary Jo Foley has spotted new evidence that suggests the company is planning to hold PDC 2011 in Seattle this year. Microsoft’s Indian Windows Azure site is currently holding a competition where contestants can win an all-expenses paid trip to PDC 2011 in Seattle.

PDC 2011 competition
Microsoft has not yet confirmed the location or timing of PDC 2011 but the company is widely expected to hold its event in September this year. Microsoft’s PDC event is aimed at software architects and professional developers who build products for Microsoft’s platforms. The company generally uses the event to reveal new versions of Windows. Microsoft unveiled Windows 7 at PDC 2008 and is expected to do the same for Windows 8 at PDC 2011.
