Client Profile Windows Presentation Foundation Business focused controls DataGrid, DatePicker, VSM  Today part of the WPF Toolkit (update in March 09)  After.NET 4.0  More controls (Chart controls, …) Silverlight Synergy (DeepZoom control ?) Win7 Advances Multitouch  Windows API CodePack for.NET (

ASP.NET MVC Separation of Concerns, Testability High control over market up ASP.NET Dynamic Data support for MVC Easily Create Custom controls and views based on data base ASP.NET better CSS and ID ASP.NET AJAX Javascript UI Templates and Databinding AJAX Control Toolkit Enhancements Client-side controls Addition of JQuery

Messaging enhancements Protocols - SOAP over UDP, WS-Discovery, WS-BusinessActivity, WS-I BP 1.2WS-DiscoveryWS-BusinessActivity WS-I BP 1.2 Duplex durable messaging RESTful enhancements Simplifying the building of REST Singleton & Collection Services, ATOM Feed and Publishing Protocol Services, and HTTP Plain XML Services using WCF  WCF REST Starter Kit released on Codeplex to get early feedbackCodeplex Correlation enhancements Content and context driven, One-way support Seemless integration with Workflow Services

XAML-only workflows are the new default Unified model between WF, WCF, and WPF Extended base activity library More activities will be present on CodePlexCodePlex WF 4.0 simplifies data flow by adding: Arguments, variables, and expressions Significant improvements in performance and scalability New FlowChart Workflow Improved WF 4.0 designer / Designer Rehosting

Stick with WF3.x workflow model Interop: Use WF3.x artifacts in WF4 solutions Rewrite WF3.x activities and workflows We will provide best practices and guidance for developing WF3.x artifacts with future migration to WF4 in mind !!!  Develop custom activities instead of relying on the WF3.x CodeActivity

There is great potential in WF + WCF.NET 3.0 didn't provide any integration.NET 3.5 added initial WCF support.NET 4.0 is investing heavily in this area  Workflow Services !!! Think "WCF on the outside, WF on the inside" WCF exposes external interface WF describes internal flow & state transitions

Microsoft Confidential IIS 7/WAS is today’s hosting environment for WCF service and WF workflows (WorkflowServiceHost class) Provides valuable hosting and management features for your WCF and WF applications Part of the Windows Server Application Server role Extensions built on top of IIS 7 with tracing, monitoring and diagnostic capabilities
