This is probably the most important Vista news so far!
WinOE or “workflow for windows”, is probably the must important capability for business announced so far for the longhorn wave:
The Windows orchestration (WinOE) code, built from the ground up by Microsoft’s BizTalk team, is a set of high level XML schemas, .NET classes, application programming interfaces (APIs) and workflow components that will allow Visual Studio 2005 developers create business processes and human-to-human workflow processes.
Microsoft will also have an add-on service available for the Longhorn client and server version of Windows in 2006 and 2007 and will make its fleet of applications including Office 12 and the next Sharepoint Portal Server “WinOE-aware,” several sources said.
