Supported Platforms : Supported Platforms Windows Vista Windows "Longhorn" Server Windows XP SP2, Windows Server 2003 SP1 Separate Install Get it via Microsoft Update, App Bootstrapper, MSI on CD, etc. ... ... just like the .NET Framework today 


Presentation Challenges : How do I improve productivity and usability? How can software exploit available hardware and form factors? How do I differentiate my software from my competition? How can my software reach the broadest possible audience? How can developers and designers collaborate? Presentation Challenges


PresentationWindows Presentation Foundation : Presentation Windows Presentation Foundation Unified approach to UI, Documents, and Media Integration as part of development and experience Integrated, vector-based composition engine Utilizing the power of the PC throughout the graphics stack Declarative programming Bringing designers directly into application development Ease of deployment Allowing administrators to deploy and manage applications securely


Integrating UI Technologies : Application Model Composable component architecture Layout engine Two-way transformable data binding Rich visual styling and theming Browser hosting Graphics Model 2D & 3D Graphics Imaging Text Video and audio Animation Document Model Fixed, flow and adaptive layouts Advanced typography Container services Rights management Integrating UI Technologies


WPF Applications : WPF Applications


Slide10 : Markup for Windows Build applications in simple declarative statements Can be used for any CLR object hierarchy Code and content are separate Streamline collaboration between designers and developers Easy for tools to consume and generate XAML


Expression Interactive Designer : Expression Interactive Designer


Introducing “WPF/E”Lightweight WPF runtime : Introducing “WPF/E” Lightweight WPF runtime Interactive experiences for devices and PC platforms Strict subset of Windows Presentation Foundation Lightweight download Programming model uses XAML + JScript Access to all WPF tooling OK LightBlue WPF-based Tools


Communication Challenges : How do I ensure reliable and secure connections? How do I manage identity and access between applications? How do I make it work over peer-to-peer and enterprise networks? How do I create applications that cross trust boundaries? How can I write one program that talks to everything? Communication Challenges


CommunicationWindows Communication Foundation : Communication Windows Communication Foundation Peer to peer infrastructure for collaborative applications PeerChannel PeerNet People near me Federated Identity Unified communication platform for distributed applications Web Services REST/POX MSMQ Channel Instrumentation and Tracing


Windows Communication Foundation : Unifies today’s distributed technology stacks Appropriate for use on-machine, cross machine, and cross Internet The unified programming model for rapidly building service-oriented applications on the Windows platform Interoperates with applications running on other platforms Integrates with our own distributed stacks Unification Integration Codifies best practices for building distributed applications Service Orientation Windows Communication Foundation


Messages & Endpoints : Client Service Messages & Endpoints Endpoint Endpoint Endpoint Endpoint


Address, Binding, Contract : Service Client Address, Binding, Contract Address Where? Contract What? Binding How? Endpoint


Contracts in WCF : Contracts in WCF [DataContract] public class Order { [DataMember] public int orderID; [DataMember] public int partNumber; [DataMember] public int price; [DataMember] public string info; } [DataContract] public class Query { [DataMember] public int orderID; } [DataContract] public class Info { [DataMember] public string info; } [ServiceContract] public interface IOrderService { [OperationContract] void Process(Order o); [OperationContract] Info GetInfo(Query q); } public class Order { public int orderID; public int partNumber; public int price; public string info; public void Process(); public GetInfo(); }

Why does Workflowmatter? : Workflow is everywhere Every “if” statement Every Web page transition Top driver of application complexity Need to take the next step Capture complex workflows Expose them to developers Enable on-the-fly extensions Why does Workflow matter?


Windows Workflow Foundation : The workflow framework & tools for Microsoft products and partner/customer ecosystem Windows Workflow Foundation Single workflow technology for Windows Base for Microsoft products and ISV/customer solutions One technology for human and system workflow scenarios A framework for building workflow into applications A framework to build on - not an application or server Exposed to developers via WinFX Brings workflow to mainstream .NET development Transform workflow from niche to mainstream paradigm Build strong partner & solution ecosystem


Windows Workflow Foundation : Windows Workflow Foundation Key Concepts Host Process Windows Workflow Foundation Runtime Engine A Workflow An Activity Runtime Services Base Activity Library Custom Activity Library Visual Designer Visual Designer: Graphical and code-based construction Workflows are a set of Activities Workflows run within a Host Process: any application or server Developers can build their own Custom Activity Libraries Components Base Activity Library: Out-of-box activities and base for custom activities Runtime Engine: Workflow execution and state management Runtime Services: Hosting flexibility and communication


Flexible Control Flow : Flexible Control Flow Rules-driven Activities Step2 Step1 Rule1 Rule2 Data Rules + data state drive processing order Data-driven Simple Conditions, complex Policies Constrained Activity Group State Machine Workflow Event Event External events drive processing order Reactive, event-driven Skip/re-work, exception handling Graph metaphor Sequential Workflow Step1 Step2 Sequential structure prescribes processing order Prescriptive, formal Automation scenarios Flowchart metaphor


Runtime Engine and Services : Host Process Workflow Foundation Runtime Engine and Services Base Activity Library My Workflow
