Software Development Trends: Service-Oriented Development Differentiated User Experience Business Process Modeling Digital Identity Management Software Development Trends


Microsoft .NET Framework 3.0: Microsoft .NET Framework 3.0 The Managed Code Programming Model for Windows


Windows Communication Foundation: Windows Communication Foundation Unified framework for rapidly building service-oriented applications


Windows Communication Foundation: Interop with other platforms ASMX WSE WS-* protocols Location transparency Remoting Unified framework supersets existing technologies Windows Communication Foundation Attribute Based Programming Message- based programming


Our Solution: Programming WCF: Our Solution: Programming WCF Classes added to the .NET Framework 2.0 … for building software services: i.e. software designed for interaction over a network with an interface described in WSDL. WSDL is as important to software as money is to the economy: it makes interactions efficient. The WCF programming model follows WSDL closely.

Windows Workflow Foundation: Programming model, engine and tools for building workflow-enabled applications Windows Workflow Foundation


What Is A Workflow?: What Is A Workflow? A Set Of Activities That Coordinates People And / Or Software... Like a flowchart…. Or a state diagram….


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


Workflow Authoring Modes: Workflow Authoring Modes .NET assembly ctor defines workflow Markup Only “Declarative” XAML Markup and Code Code Only Application Generated XAML XML defines workflow structure logic and data flow XML defines workflow Code-beside defines extra logic Code creates workflow in constructor XAML App creates activity tree and serializes Workflow Compiler wfc.exe C#/VB Compiler


What are Activities?: What are Activities? An activity is a step in a workflow Has properties and events that are programmable within your workflow code Has methods (e.g. Execute) that are only invoked by the workflow runtime Think of Forms & Controls Activity == Controls Workflows == Forms Activities fall under two broad categories Basic – steps that “do work” Composite – manage a set of child activities


Activities: An Extensible Approach: Activities: An Extensible Approach OOB activities, workflow types, base types General-purpose Activity libraries define workflow constructs Create/Extend/ Compose activities App-specific building blocks First-class citizens Base Activity Library Custom Activity Libraries Out-of-Box Activities


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

Windows Presentation Foundation: Windows Presentation Foundation Unified framework for building next gen user experiences with UI, media and documents


Windows Presentation Foundation: Windows Presentation Foundation XAML eXtensible Application Markup Language


Windows Presentation Foundation: Windows Presentation Foundation With XAML designers & developers can streamline their collaboration


Slide35: What is WPF? Windows Presentation Foundation is one of four principal components in .NET 3.0 WPF is essentially an alternative method for developing Windows based applications


WPS vs Windows Forms Development: WPS vs Windows Forms Development WPF has a number of advantages over Windows Forms development which include Comprehensive Integration – WPF provides a uniform platform for using video, speech, text, 2D and 3D graphics Resolution Independence – as DPI increases, WPF applications maintain their size exactly Instead of shrinking, WPF applications merely get Sharpe


WPF Advantages over Windows Forms Development: WPF Advantages over Windows Forms Development WPF supports hardware acceleration WPF applications can take advantage of GPUs on Graphics cards for smoother graphics WPF allows the effective separation of design work (to be performed by Designers) and functionality (to be performed by Developers)


WPF Advantages over Windows Forms Development: WPF Advantages over Windows Forms Development WPF supports a new model for content under which almost any control can host almost any other control This permits very rich user interfaces as almost any control can support 3D graphics, animations and even videos WPF supports almost complete scalability


WPF and XAML: WPF and XAML XAML is a declarative programming language designed for constructing and initializing .NET objects XAML code is principally the textual representation of some visual element – either a graphic object or a user interface object such as a button or a combo box


WPF and XAML: WPF and XAML Under the standard paradigm the User Interface is described in XAML and the underlying functionality is built using C# (or Visual Basic .NET) However, using Markup Extensions Microsoft has cleverly been able to build a considerable degree functionality into XAML Usually when things can be expressed in either C# or XAML, XAML is more terse


What is WPF/E: What is WPF/E WPF/E stands for WPF Everywhere WPF/E is basically a Microsoft equivalent for Macromedia Flash Currently only in beta form, WPF supports Fire fox and Internet Explorer 7 on Windows and Fire fox and Safari on the MAC


What is the Relationship Between WPF/E and WPF: What is the Relationship Between WPF/E and WPF WPF/E uses a Javascript control to host content created using XAML Recall that vector graphics can be expressed in XAML and that WPF has very strong support for animations Client side event handling is processed using JavaScript


What is the Expressions Suite: What is the Expressions Suite The Expressions Suite consists of four designer type applications Only one of these applications, Expressions Web Designer has been officially released (January, 2007) The other three releases are currently in beta release (or CTP)


Expressions Web Designer: Expressions Web Designer This product is essentially the successor to Microsoft Front Page Its principal competitor is Macromedia (Adobe) DreamWeaver The emphasis by Microsoft for this product is Standards Based web design (XHTML) This product has nothing at all directly to do with WPF


Expressions Blend: Expressions Blend Expressions Blend is a Visual Studio like tool for designing WPF user interfaces While Blend is intended for use by Designers, it is sufficiently superior to the equivalent designer in Visual Studio that most Developers will likely use it in conjunction with Visual Studio


Expressions Graphic Designer: Expressions Graphic Designer This product represents Microsoft’s attempt to move into the space occupied by Adobe Illustrator and CorelDraw Vector Graphics Graphic Designer uses XAML as its native output language This, of course, facilitates using these vector graphics in WPF applications


Expressions Media: Expressions Media The latest addition to the Expressions suite Represents a content management system similar to Adobe Bridge No direct relationship with WPF


Windows CardSpace: Windows CardSpace Private desktop Separate user context Protects against hacking Self-issued cards Non-corroborated Stored locally Managed cards Corroborated Stored at STS


Windows CardSpace: WS-* Web Services Windows CardSpace


Introduction to Windows CardSpace: Introduction to Windows CardSpace Windows CardSpace is client software that enables users to provide their digital identity to online services in a simple, secure and trusted way. It is what is known as an identity selector The CardSpace UI enables users to create Personal cards (aka self-issued cards) and associate a limited set of identity data.


Windows CardSpace: Windows CardSpace The architecture upon which CardSpace has been built – consisting of subjects, identity providers and relying parties – is called “The Identity Metasystem”.
