"Stay hungry, stay foolish", Steve Jobs (1955 - 2011)

One of the greatest challenges facing development teams, or individual departmental developers, is the integration of business logic or rules into an application. This CodePlex project introduces how to integrate SharePoint 2010 and Office Open XML into Office applications that are backed by Windows Workflow 4.0 (WF4). Using WF4 with custom SharePoint and Open XML activities simplifies coding by providing reusable code activities that can be dropped into workflow-driven business logic. Think of Office workflow activities as giving you plug-in business logic for a Word or Excel solution.

The vision is decoupled Office / SharePoint Windows Workflows that run on existing Office 2007 and 2010 desktops that can transition to future cloud offerings.

Windows Workflow 4.0 with SharePoint 2010 and Office Overview

The project is divided into two phases. Phase I is focused on Windows Workflow 4.0 activity designers that use the SharePoint 2010 Client Object Model, Office Open XML and XSLT Content Transforms to enable client-side business / content workflow tools. Phase I is the tools side or Office desktop workflow side of the project. Phase II will focus on Silverlight web applications that consume SharePoint / Office based workflows from Windows Workflow 4.0 WCF-based web services.
