The document discusses new features and capabilities in Microsoft technologies including Windows Communication Foundation (WCF), Windows Server App Fabric, Windows Workflow Foundation (WF), and Silverlight. Key points include: - WCF 4.0 includes improvements to configuration, monitoring, routing, and discovery. Windows Server App Fabric provides hosting and management of WCF and WF services. - App Fabric supports WCF and WF services through runtime databases and capabilities for monitoring, persistence, hosting, caching and management tooling. - Workflow services are well-suited for business processes. App Fabric supports durable workflows through persistence of instance state and recovery. - Silverlight 4 beta includes new media and interaction features such as printing, dragging
