2 At one point, the Component Object Model COM and ActiveX were made to work across platforms, but they have long since been relegated to Windows only.At the other extreme we have WPF, a completely new managed framework built on top of DirectX. WPF encompasses documents, layout, animation, 2-D, 3-D, text, and graphics primitives in a single, cohesive whole. This framework provides the richest client technology that Microsoft has ever built, and it takes maximum advantage of the platform on which it runs, including any hardware 3-D graphics acceleration that may be available. However, at the time of this writing, WPF has not yet shipped and works only under Windows XP, Windows Server 2003, and Windows Vista.3
3 WinFX which inclues WPF and Windows Vista are scheduled to ship in 2006.Where does that leave Windows Forms 2.0? It doesn''t quite offer the richness of WPF, but it''s far richer than the HTML-based technologies. Windows Forms 2.0 also is much richer than Windows Forms 1.0, with greatly enhanced support for flexible layout, modern menu strip and tool strip controls, data binding, multithreading, typed resources and settings, and, most importantly, ClickOnce deployment. With ClickOnce, for the first time, users can deploy Windows applications as easily as web applications. Even better, ClickOnce allows Windows applications to be installed locally, integrated with the Start menu, and accessed even if no network connection is available. These options are not available for users of Web applications. So Windows Forms 2.0 is high on the richness scale, but what about the reach scale? Unlike web applications, Windows Forms requires that users'' machines operate on Windows, specifically Windows 98 or later for PCs. However, it also supports other devices, such as Pocket PCs or Smartphones, via the .NET Compact Framework. This means that you can write a Windows Forms 2.0 application and run it on your Windows smartphone. Based on this level of richness and reach, what kinds of applications should you build with Windows Forms? As it turns out, folks have used Windows Forms to build almost every kind of application, including productivity applications, utilities, enterprise tools, and more-even games. Windows Forms can be used to build smaller things, such as Microsoft''s own internal human resources application called HeadTrax , or larger things, such as most of the UI enhancements that have been built on top of Visual Studio since the 2002 edition. This range of applications can be built because of Windows Forms'' range of features and tools, its reach, and, as of this version, the maturity of the implementation based on community usage and feedback. In fact, the .NET developer community has embraced Windows Forms to a degree that defies the early .NET focus on web-based applications. Based on talking to my friends in Less
