  • In 2001, we introduced .NET Framework. In Nov 2005, we released .NET Framework 2.0. Yet, there was a need to offer our customers additional functionality, such as better user experience in software and workflow. With Windows Vista, we are introducing Microsoft ® .NET Framework 3.0 (formerly named WinFX). .NET Framework 3.0 builds upon .NET Framework 2.0, with additional capabilities, such as Windows Presentation Foundation (WPF), Windows Communication Foundation (WCF), Windows Workflow Foundation (WF), and “Infocard.”
  • Windows Presentation Foundation (WPF) is a productive, unified approach to UI, Media, and Documents that you can use to deliver unmatched user experiences to your customers.
  • Open Document Specifications Open Packaging Conventions and XML Paper Specification (XPS) for use by devices and any application on any platform. WPF Document APIs Application programming interfaces (APIs) to manage package and content. XPS Print Path Print pipeline with XPS spool format and printer-page description language to speed and improve print job fidelity. New driver model. Print Driver for “Save As” A print-to-file converter for creating XPS Documents from any Microsoft Windows-based application. XPS Viewer A WPF utility that allow users to view, protect and print XPS Documents. Hosted in IE.
  • Let’s look at the WPF support for 2D and 3D graphics, and imaging. Graphics - The following areas comprise the Windows Presentation Foundation graphic APIs. Brushes.  Use the Brush classes to paint areas with solid colors, patterns, images, and drawings. Shapes.  Use Shape classes to create and render 2-D geometric shapes. Imaging.  Use the imaging classes to encode, manipulate, and displays bitmaps, and to apply special effects such as glow and blur to images and vectors. Geometries.  Geometries, like shape objects, represent 2-D shapes. Geometries are more versatile than shape objects, in that they can be used to define curves, clipping regions, and hit-testing areas. Unlike shape objects, geometries do not participate in the layout system and cannot draw themselves to the screen. They can be rendered using other framework elements, controls, visuals, or brushes. Transformations.  Use the Transform classes to rotate, translate, scale, and apply other 2-D effects to geometries, visuals, brushes, framework elements, and controls. Animations.  Use the animation and timing APIs to make objects change color, move, spin, grow, shrink, and more. Visuals.   Visual objects are the building blocks of the Windows Presentation Foundation rendering system. The visual layer is the Windows Presentation Foundation equivalent to GDI. All Windows Presentation Foundation objects use visuals to draw to the screen. 3-D Graphics - The System.Windows.Media.Media3D namespace defines 3-D graphics primitives, transformations, and animations that can be used to create 3-D controls and graphics. Imaging Platform Basics Not the mainstream WPF usage, but critical for a class of customers Industrial strength, used extensively in the Windows Vista Shell 3rd party extensible bitmap CODEC architecture Microsoft-supplied CODECs for JPEG, TIFF, PNG, GIF, BMP, ICO Streams and NT Sections Thumbnails in the Windows Vista shell “ Mainline” encode / decode, explicit imaging operations, etc. Access through managed and native code Imaging engine in Windows Vista, can be used by Win32
  • WPF is the next-generation Windows smart-client UI technology: Immersive Desktop applications – Includes rich ISV and LOB applications that can be deployed to Windows as a stand-alone client. Enterprise Intranet applications – A unique capability of WPF is that you can use the same code base to deploy a WPF app either as a stand-alone desktop client, or in the browser. This lets you maintain just one code base for enterprise applications that are needed in both deployment models - stand-alone and in the browser. This dramatically lowers TCO. Windows Media Center applications - Current Media Center spotlight apps are created mostly in DHTML. WPF offers a much more sophisticated visual toolbox to create a great user experience that scales to different form factors (from CRT monitors to laptop LCDs to big screen TVs), thanks to its DPI-independent resolution. End-users using Media Center Extender can also navigate using their remote controls Now that’s user experience! Premium Internet applications – As consumers, we may often be avid “super” users of certain internet applications, while at the same time being just casual users of most other internet applications. As avid users, we often expect an exclusive user experience that’s better than the norm. WPF (that is XAML Browser Applications or XBAPs), through its UI and media integration (audio, video, sound, animation, 2D, 3D, document services, styling, data binding, etc.), is a great platform to build these rich internet applications, where exclusivity is a requirement.
  • WPF supports the following audio/video formats. Windows Media Video (. wmv ) files are Advanced Systems Format (.asf) files that include audio, video, or both compressed with Windows Media Audio (WMA) and Windows Media Video ( WMV ) codecs. MPEG (pronounced M-peg), which stands for Moving Picture Experts Group , is the name of family of standards used for coding audio-visual information (e.g., movies, video, music) in a digital compressed format. The major advantage of MPEG compared to other video and audio coding formats is that MPEG files are much smaller for the same quality. This is because MPEG uses very sophisticated compression techniques. AVI , an acronym for Audio Video Interleave , is a multimedia container format introduced by Microsoft in November 1992 , as part of the Video for Windows technology. AVI files contain both audio and video data in a standard container that allows simultaneous playback.
  • WPF supports ClearType fonts, which results in better readibility and comprehension. Notice the difference between the upper text and the bottom text. WPF also supports alti-aliasing, which rounds off rough pixel edges. This again results is better content readibility and comprehension. Subtle but important text features like this add up to provide customers will a great online reading experience.
  • ARCHITECTURE: This diagram shows the basic architecture for WPF. Notice all the different media types (in yellow) that are handled by WPF: Vectors, Bitmaps, 3D, Audio and Video, Text and Effects! Second, notice how the animation capabilities of WPF spans across all the media types, allowing you to animate any kind of content. The WPF Composition Engine (in black) is one of the revolutionary features of WPF. This engine provides capability of having live content inside of another content. This means that you can have a 3D object rotating inside a Button control and furthermore you can have a video projected over the surface of the 3D object! This tree structure and nesting capability is available for all content and every control that WPF provides. WPF is not only about rich user interfaces but also about high fidelity information, connection and data. Controls, Layout and Databinding are just some of the examples of this power. The XPS format is a rich document definition that allows us to enjoy the best of WPF in a document. In summary, WPF represents an evolution in terms of richness, interactivity as well as information and data. DESIGN PRINCIPLES - The design principles behind Windows Presentation Foundation can be categorized as follows: Integration : Windows Presentation Foundation offers a unified API that spans the services identified in Table 1. Developers today are faced with a myriad choice of disparate technologies and APIs, depending on whether they are targeting 2D graphics (GDI or GDI+), user interface (USER32 or Windows Forms), media (DirectShow), or 3D (Direct3D or OpenGL). Windows Presentation Foundation provides a single model that is orthogonal across all these services and allows seamless integration of content within a single application. You can use the same constructs for animation, data binding and styling, regardless of whether you are targeting 2D, 3D or text content. Vector graphics. As described in the introduction, Windows Presentation Foundation takes full advantage of the powerful Graphical Processing Units that are part of modern PC systems. At its heart, the composition engine is vector-based, allowing for scaling of all output to match the resolution of a specific machine. The rendering architecture uses Direct3D for all output: on video cards that implement DirectX 7 or later in hardware, Windows Presentation Foundation renders output using the GPU wherever possible. In situations where hardware rendering cannot be used, software rendering is available as a fallback. Lastly, a floating-point logical pixel system and 32-bit ARGB color support provide a rich high-fidelity experience that anticipates future technology needs, such as high-DPI displays. Declarative programming. Windows Presentation Foundation introduces XAML (eXtensible Application Markup Language), an XML-based language for instantiating and populating nested object hierarchies. While XAML isn't exclusively tied to Windows Presentation Foundation, it is inherently suitable for tasks such as UI definition and construction. The design of XAML allows applications to parse and manipulate UI logic at run-time for dynamic workflow scenarios. Importantly, the XAML / code-behind model embodied in Windows Presentation Foundation allows designers and developers to work collaboratively on client application design and development, using tools such as Expression "Sparkle" as well as third-party specialist tools including ZAM 3D and Mobiform Aurora. Easy deployment . With support for both standalone applications and Web-browser applications, Windows Presentation Foundation offers the best of both deployment models. Web-browser applications run from within Internet Explorer, either occupying the entire window or within an inline frame. They offer the ease of deployment for which Web applications are famed, as well as operating within a partial trust sandbox that protects the client machine against malicious applications. Yet they can still take advantage of the local client hardware and use 3D and media services for the richest Web experience available today. On the other hand, standalone applications are locally installed via ClickOnce or MSI technologies and offer full access to the underlying platform. Document lifecycle. Windows Presentation Foundation introduces a new set of document and print technologies. Applications that need to persist data to a local store can use the Open Packaging Conventions , a ZIP-based packaging convention shared with Office 12 that supports core properties and custom metadata, digital signatures and rights management functionality. For applications that want to share documents for collaboration across multiple machines, even without the application installed, the XML Paper Specification allows visuals to be fixed in a printable, portable format.
  • If user experience matters, design matters. If design matters, designers matter. If designers matter, we need to make designers first class citizens of the traditional software development process. Let’s talk about how Microsoft is unlocking Developer and Designer collaboration and is empowering them to create successful UX software applications. 1) Traditionally designers would “mockup” the graphic design for a software application. Then by any means possible designers would deliver this “looks” to the developer… they would use JPG images, PNGs, PSDs or even Powerpoint presentations to express the designer intention. Then the developer would receive this “static images” and would try to convert that into reality. If the designer created some “non standard” controls, the developer was forced to code in GDI+ or other complex technologies to create the control raising the time and budget to such level that it was simply better to take the decision of making the UI more “standard”. The developer trying to recreate the idea of the designer would deliver something like what is shown on the right side of the screen. As you can see it represents only a tiny bit of the original vision. 2) In order to enable the collaboration between developers and designers, Microsoft has created XAML. XAML is the format which integrates the development process and is the way for both developers and designers to access the functionalities of WPF. As you can see we have no middle man anymore. XAML is generated by the designer, XAML is consumed by the developer. Further more, the workflow is now two-way meaning that the development process can also start from the developer side who creates XAML and then delivers this XAML to the designer which can take it and style it or completely redesign its appearance. 3) As a brief sample this are the tools that enable this kind of process: On the designer side we have Expression and on the Developer side we have Visual Studio.
  • Stands for Extensive Application Markup Language Easily toolable, declarative markup 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 Developers add business logic, while designers design Can be rendered in the browser (as part of a web page) or as a standalone application XAML WPF introduces a new role to the rich client software development team – that of professional designer. Gone are the days of boring gray buttons and poorly designed applications: with the declarative programming model enabled by XAML, you can split off presentation and logic in the same way as with a web application. XAML is a markup language that is inherently toolable, allowing for designers and developers to use independent tools. XAML (which stands for "Extensible Application Markup Language") provides an XML-based way to specify declaratively a hierarchy of objects with properties and logic. We're positioning XAML as a user interface design language, because it is ideal for generating the kind of code that traditionally resided in a hidden #region area and was hard to maintain by both developers and tools. If you've ever wanted to edit the auto-generated blocks of code created by Visual Studio but been dissuaded by the warning comments writ large, or you've gone ahead regardless and been burnt badly when your tools refused to load your changes, you'll appreciate XAML. XAML is not Avalon, and Avalon is not XAML. It so happens that they come out of the same team at Microsoft, but they are not intrinsically wedded together. I've been asked before "where can I go to get the XSD for XAML?" and hopefully it's now clear that this question doesn't make much more sense than asking for the C# schema. XAML gets compiled into an object definition.
  • Controls: WPF provides a rich set of controls – Border , BulletDecorator , Button , Canvas , CheckBox , ComboBox , ContextMenu , Control , DockPanel , DocumentViewer, Expander , FlowDocumentPageViewer , FlowDocumentReader , FlowDocumentScrollViewer , Frame , Grid , GridSplitter , GridView , GroupBox , Image , Label , ListView , ListBox , Menu , Panel , PasswordBox , Popup , Tooltip, etc…. Animation, Triggers and Timelines – In the illustration above, "Start" refers to an ellipse, MouseDown describes an event, and "Resume" describes the action that will be taken on the timeline "OnLoaded" when that event occurs. These 3 pieces make up a trigger. All this can be accomplished using a timeline, such as one shown above in Microsoft Expression Interactive Designer. Styles and Resources – Styles c entrally define the appearance and interactive behaviors of the elements in your app. A resource is an object defined within an application based on Microsoft® Windows® Presentation Foundation (WPF) for the purpose of re-using the resource in different places. One of the most common uses of a resource is in re-using a color in different controls. You can change the color of the resource once and see the changes affect any controls that linked to it. Changing one asset with multiple relationships is easier than replacing many instances of data that has been copied and pasted several times. Resources can be applied to any kind of value, such as text, numbers, styles, templates, and complex objects. An external resource dictionary is a file that represents a set of resources. This file can be used in any project by linking to the resource dictionary from a scene or application. External resource dictionaries enable other applications to export re-usable assets which can then be imported into Microsoft Expression™ Interactive Designer. These external resource dictionary files allow designers and developers to re-use the same asset across multiple applications based on WPF. Layout panels let you position elements within a window Different layout panels Canvas – for specifiying exact (x,y) positioning DockPanel – for docking elements without worrying about exact (x,y) positioning StackPanel – for stacking elements from left to right or from top to bottom Grid – for row/grid positioning, while specifying column and row definitions WrapPanel - models the right hand pane of an Explorer window, allowing you to handle items that flow over to a new row when the current row is full
  • Serialize WPF content to XPS Application/activity easily creates XPS file from WPF elements Create/Use XPS Documents Workflow activity or desktop application edits or creates XPS Documents; includes support for Package services for XPS Documents Create/Use Package Activity or application opens package and reads/changes/adds parts and relationships , Digital Signatures and Metadata Use Custom Viewer Application includes viewer control that displays XPS pages and WPF content Create/Use Documents w/ Restricted Permissions Application interacts with Windows RMS to create or consume Open Packaging Convention documents with restricted permissions
  • Data binding is the process that establishes a connection between the application UI and business logic. A typical use of data binding is to place server or local configuration data into forms or other UI controls. In Windows Presentation Foundation, this concept is expanded to include the binding of a broad range of properties to a variety of data sources. In WPF, dependency properties of elements can be bound to CLR objects (including ADO.NET objects or objects associated with Web Services and Web properties) and XML data. Dependency properties are properties that are registered with the Windows Presentation Foundation (formerly code-named "Avalon") dependency property system. You can take advantage of the dependency property system in the following ways: By backing your common language runtime (CLR) property with a dependency property. This allows your property to have support for styling, databinding, animation, initial default values, value expressions, property invalidations, or inheritance. Examples of dependency properties include the Background property and the FontSize property. By creating attached properties. Attached properties are properties that can be set on any DependencyObject types. An example attached property is the Dock property. OneWay binding causes changes to the source to automatically update the target, but changes to the target are not propagated back to the source. This type of binding is appropriate if the control being bound is implicitly read-only. For instance, you may bind to a source such as a stock ticker or perhaps your target property has no control interface provided for making changes, such as a data-bound background color of a table. TwoWay binding causes changes to either the source or the target to automatically update the other. This type of binding is appropriate for forms or other fully interactive UI scenarios. Most properties default to OneWay binding, but some dependency properties (typically properties of user-editable controls such as the Text property of TextBox and the IsChecked property of CheckBox ) default to TwoWay binding. A programmatic way to determine whether a dependency property binds one-way or two-way by default is to get the property metadata of the property using GetMetadata and then check the boolean value of the BindsTwoWayByDefault property. OneWayToSource is the reverse of OneWay binding; it updates the source when the target changes.
  • You can incrementally embrace WPF, w/o throwing away your existing code base or skill set. WPF-Windows Forms Interoperability Host WPF controls in a Windows Forms application using WindowsFormsHost Host Windows Forms controls in a WPF application using ElementHost Augment the WPF features with Windows Forms features WPF-HWNDs Interoperability WPF & HWNDs enable WPF interoperability with Win32, MFC, Active Template Library, ActiveX & DirectX Use HWNDSource to host WPF inside HWNDs & to host HWNDs inside WPF
  • WPF is Microsoft’s strategic presentation technology for Windows smart client user experiences. Use WPF to deliver innovative user interfaces through support for UI, media, document services, hardware acceleration, vector graphics, resolution-independent DPI for different form factors, data visualization, and superior content readability. Increase developer-designer productivity and collaboration through Visual Studio, Microsoft Expression Interactive Designer, and XAML. Write code once, and deploy as stand-alone client or in a browser. Incrementally embrace WPF through interoperability with Win32 and Windows Forms. Leverage vested knowledge in .NET Framework, CLR languages and Visual Studio IDE. Derive business value through new paradigms of user experiences, business intelligence through data visualizations, brand awareness through differentiated customer experiences, and customer loyalty through higher customer satisfaction.
