We discuss SharePoint 2013 Workflow in depth from Developer Point of view first then we talk about in Details new  Architecture of SharePoint Workflow. thanks to All Community Members for Participating Especially MVP venkatanarasimha.kl  and MCTs (Fahad khan and Wasi) for Sharing their Knowledge with us. 2nd Part of Workflow Session will be online in upcoming week.  also we share some great learning resources free channel downloaded videos and learning content on sky drive and give one Pluralsight training Vouchers. hope we will keep motivating UAE community for more SharePointing.
