Windows Presentation Foundation Goal Illustrating the Problem Suppose a hospital wants to create a new application for examining and monitoring patients. The requirements for this new applications user interface might include the following: Displaying images and text about the patient. Displaying and updating two-dimensional graphics showing the patients vital signs, such as heart rate and blood pressure. Providing three-dimensional views and overlays of patient information. Presenting video of ultrasounds and other diagnostics, perhaps allowing physicians and nurses to add annotations. Allowing hospital staff to read and make notations on documents describing the patient and her condition. Running both as a Windows application, allowing full capability for hospital employees, and in a security-restricted Web browser application, allowing more limited access by remote physicians via the Internet. Changing Perspective User interfaces that present the right information in the right way at the right time can have significant business value. Modern applications can benefit from providing interfaces that integrate graphics, media, documents, and the other elements of a modern user experience. The Hurdles Variety of technology : difficult to find developers. Designing an interface that effectively presents all of this functionality to users is challenging. Professional designers are required—software developers dont have the right skills—but designers and developers face significant challenges in working together, especially with full-featured interfaces like the one described here. The Hurdles Offering a full-featured interface as both a standalone Windows desktop application and a browser-hosted version would require building two separate implementations using two different sets of technology. The Windows desktop application would likely use Windows Forms and other native Windows technologies, while the browser-hosted application would use HTML and JavaScript
