In this book, two leading Windows Presentation Foundation experts give developers everything they need to build next-generation WPF applications - software that is more robust, usable, and compelling. Programming Windows Identity Foundation. Get hands-on guidance designed to help you put the newest.
NET Framework component - Windows Identity Foundation, the identity and access logic for all on-premises and cloud development - to work Although this enables C developers to use DirectXwithout most of the complications of. So although you could have developed a Windows-based email program with the 3Deffects seen in Disclosure ever since the mids with non-GDI technologies actually,probably mixing DirectX or OpenGL with GDI , such technologies are rarely used inmainstream Windows applications even a decade later.
There are several reasons for this:The hardware required to get a decent experience hasnt been ubiquitous until recently, ithas been at least an order of magnitude harder to use alternative technologies, and GDI-based experiences have been considered good enough. Graphics hardware continues to get better and cheaper and consumer expectationscontinue to rise, but until now, the development experience has not improved signifi-cantly.
In recent years, developers started to take matters into their own hands to getcustom-branded applications and controls on Windows. A simple example of this is usingbitmaps for buttons instead of the standard button control.
These types of customizationscan not only be expensive to develop, but they also often produce a flakier experience. Such applications often arent as accessible as they should be, cant run in partial-trustenvironments, dont render well over Remote Desktop, dont handle high dots-per-inch DPI settings very well, and have other visual glitches. Windows Presentation Foundation WPF is the answer forsoftware developers and graphic designers who want to create modern user experienceswithout having to master several difficult technologies.
Although Presentation soundslike a lofty term for what I would simply call a user interface, its probably more appropri-ate for describing the higher level of visual polish thats expected of todays applicationsand the wide range of functionality included in WPF. Broad integrationPrior to WPF, a Windows developer who wanted to use 3D,video, speech, and rich document viewing in addition to normal 2D graphics andcontrols would have to learn several independent technologies with a number ofinconsistencies and attempt to blend them together without much built-in support.
But WPF covers all these areas with a consistent programming model as well as tightintegration when each type of media gets composited and rendered. You can applythe same kind of effects consistently across different media types, and many of thetechniques you learn in one area apply to all the other areas. Resolution independenceImagine a world in which moving to a higher resolu-tion or DPI setting doesnt mean that everything gets smaller; instead, graphics andtext simply get crisper!
WPF makes this easy, and gives youthe power to shrink or enlarge elements on the screen independently from thescreens resolution. A lot of this is possible because of WPFs emphasis on vectorgraphics. This impact can be easily seen with the Windows Vista Magnifier applica-tion, which has intrinsic support for WPF vector graphics.
Figure 1. Notice the smoothscaling of the two WPF buttons compared to the jagged enlargement of the non-WPF combobox and tab control border and even the mouse pointer! Specifically, content in a WPF applicationwhether 2D or 3D, graphics,or textis converted to 3D triangles, textures, and other Direct3D objects and thenrendered by hardware.
This means that, unlike GDI-based systems, WPF applicationsget the benefits of hardware acceleration for smoother graphics and all-aroundbetter performance due to work being off-loaded to graphics processing units[GPUs] instead of central processor units [CPUs].
It also ensures that all WPF appli-cationsnot just high-end gamesreceive the maximum benefit from new hard-ware and drivers, whose advances typically focus on 3D capabilities. But WPFdoesnt require high-end graphics hardware; it has a software rendering pipeline aswell.
This enables features not yet supported by hardware, enables high-fidelityprinting of any content on the screen, and is used as a fallback mechanism whenencountering inadequate hardware resources such as an outdated graphics card oreven a high-end one that has simply run out of GPU resources such as videomemory.
And although Windows Forms doesnt have built-in support for declarative userinterface definitions,. The result is that graphic design-ers are empowered to contribute directly to the look and feel of applications, as wellas some behavior for which youd typically expect to have to write code.
The nextchapter examines XAML in depth. Rich composition and customizationWPF controls are extremely compos-able in ways never before seen. You can create a ComboBox filled with animatedButtons, or a Menu filled with video clips! Although these particular customizationsmight sound horrible, its important that you dont have to write a bunch of code or any code!
Along the same lines, WPF makes itquite easy to skin applications with radically different looks covered in Chapter10, Styles, Templates, Skins, and Themes. Easy deploymentWPF provides options for deploying traditional Windowsapplications using Windows Installer or ClickOnce or hosting applications in aweb browser. Although most of this support isnt new to WPF these options are alsoavailable for Windows Forms , its still an important component of the technology. One new and interesting aspect is that WPF builds on top of ClickOnce for support-ing direct integration with a web browser and its navigation system covered inChapter 7, Structuring and Deploying an Application.
The firstversion of WPF does a good job at realizing this goal, although its not perfect, of course. You might run into some performance issues such as poor startup time or certain visualeffects that are not hardware accelerated or areas where the feature set isnt quite ascomplete as youd like such as in 3D, audio, and video. But with the help of this book, Ithink youll find that WPF gives you more productivity, power, and fun than any othertechnology that youve worked with in the past!
DirectX is definitely not dead and is still more appropriate than WPF for advanced developerswriting hard-core twitch games or applications with complex 3D models where you needmaximum performance. That said, its easy to write a naive DirectX application that performsfar worse than a similar WPF application.
DirectX is a low-level interface to the graphics hardware that exposes all of the quirks ofwhatever GPU a particular computer has. DirectX can be thought of as assembly language inthe world of graphics: You can do anything the GPU supports, but its up to you the applica-tion author to support all the hardware variations. This is onerous, but such low-level hard-ware access enables skilled developers to make their own tradeoffs between fine-grainedquality and speed.
In contrast, WPF provides a high-level abstraction that takes a description of your scene andfigures out the best way to render it, given the hardware resources available. Internally, thismight involve using Shader Model 3. Dont worryif youre not familiar with these terms, but take it as a sign that you should be using WPF! The downside of choosing DirectX over WPF is a potentially astronomical increase in develop-ment cost.
One of the major benefits of building on top ofWPF is that Microsoft has already done this testing for you! You can instead focus yourtesting on low-end hardware for measuring performance. The fact that WPF applications caneven leverage the client GPU over Remote Desktop or in a partial-trust environment is also acompelling differentiator. Technically, the answer is No, just like C and the.
NET Framework dont enable you to dosomething that you couldnt have done in assembly code. Its just a question of how muchwork youre willing to do to get the desired results! If you were to attempt to build a WPF-equivalent application from scratch without WPF, youdnot only have to worry about the drawing of pixels on the screen and interaction with inputdevices, but youd also need to do a ton of additional work to get the accessibility and local-ization support thats built in to WPF, the special handling of Remote Desktop built in to WPFso that remote applications can be rendered on the client to avoid a variety of performanceissues, and so on.
Note that the optimized Remote Desktop experience only works when theserver is running Windows Vista or later and the client has WPF installed. So, I think most people would agree that the answer is Yes after you factor time and moneyinto the equation!
WPF is clearly more suitable for applications with rich media, but some people have said thatWindows Forms is the best choice for business applications with traditional user interfaces. Although Windows Forms still has useful controls that WPF lacks such as DataGridView andPropertyGrid and at the time of writing has a larger set of third-party controls in themarketplace, WPF has compelling features even for traditional user interfaces such as thesupport for resolution independence or advanced layout.
So unless running on Windows 98 is important which is still supported by Windows Forms2. But Windows Forms isntgoing away anytime soon; there just wont be major enhancements made to it after version2. For creating rich web content, Flash is currently the most popular option because of its ubiq-uity. You can put Flash-based content on a website with confidence that the overwhelmingmajority of visitors already have the necessary player installed.
And if they dont, its a veryquick download. WPF applications can also run within a web browser. WPF has the advantage of better devel-opment tools and programming model, a richer feature set, robust control reuse, broadprogramming language support, and full access to the underlying platform when securitypermits.
