I'm looking for a step-by-step guide to consuming and calling WCF or web services from a BizTalk 2010 Orchestration. I've read a lot of articles that contradict each other and none of them work when I try to implement them in Visual Studio 2010. any help is greatly appreciated.
Some more specifics:
I need to use the Lists web service in SharePoint to query list items
Based on the results of that query, call a custom WCF service somewhere else
