This unit describes key Windows Azure components and features and identifies integration points and common solution patterns for combining SharePoint 2010 and Windows Azure.
Consuming Windows Communication Foundation Services From SharePoint 2010 and InfoPath 2010
Consuming Windows Azure-Hosted WCF services from SharePoint is easily accomplished via a Silverlight application running in a Silverlight Web Part. In fact, from the perspective of SharePoint and Silverlight it is no different from consuming a WCF service which is not hosted in Windows Azure. In this lab you will learn how to create a basic WCF service in a Windows Azure web role. You will also learn how to create a cross-domain policy file which enables Silverlight applications to call outside of the site in which they're deployed, enabling access to cloud services. Finally, you will learn how to reference a WCF service in the cloud from a Silverlight application, and display that application in a Silverlight web part in SharePoint.
