these support files could easily be installed on top of each other, a common occurrence leading to broken applications (called DLL hell). The second problem was security. A user s computer, when connected to the Internet, could effectively allow code to run, written by anybody, and the ActiveX technology was fully native, not restricted by the Java or HTML sandboxes (more about these in a moment); therefore, a user could innocently go to a web page that downloaded an ActiveX control that wrought havoc or stole vital information from their system. As such, many users refused to use them, and many corporate administrators even disallowed them from use within the enterprise. The virtual nature of Java and HTML where applications and pages were coded to work on a specific virtual machine offered better security; these machines couldn t do anything malicious, and therefore applications written to run on them couldn t either. The users were effectively safe, though limited in the scope of what they could do. At the end of the 1990s, Microsoft unveiled the successor to ActiveX (amongst others) in its Java-like .NET Framework. This framework would form Microsoft s strategic positioning for many years. Like Java, it provided a virtual machine the common language runtime (CLR) on which applications would run. These applications could do only what the CLR allowed and were called managed applications. The .NET Framework was much more sophisticated than the Java virtual machine, allowing for desktop and web applications with differing levels of functionality (depending on which was used). This was part of managing the code. With the .NET Framework came a new language, C#, but this wasn t the only language that could be used with .NET it was a multilanguage, single-runtime platform that provided great flexibility. The .NET Framework was revolutionary because it united the client-application experience and the connected-application experience across a unified runtime that ActiveX tried but ultimately failed to do. Because the same platform could be written for both, the result was that the user experience would be similar across both (see Figure 1-7). Coupled with the emergence of Extensible Markup Language (XML), a language similar to HTML but specialized for handling data instead of presentation, web application development was finally coming of age.

Figure 1-7. The .NET Framework provides consistent browser, desktop, and server application programming interfaces (APIs). Thus, the pendulum has swung back toward the thin client/fat server approach. Ironically, the thin client is probably fatter than the original servers, because it s an operating system that can support a browser that is extended to support XML (through parsers), scripting (through interpreters), and other plug-ins, as well as Java or .NET virtual machines!

With all these runtime elements available to developers and a consistent server-side API (through the .NET Framework or Java server side), rich, high-performing applications built on a client/server model are now fully possible. And here is where you have to decide how you develop your client applications. One set of technologies based on HTML, DHTML, Asynchronous JavaScript and XML (Ajax), and Microsoft ASP .NET Atlas gives you the same level of sophistication that a heavy client can give you using light technologies. Features such as asynchronous updates, slick user interfaces, handy tooltips, and other embellishments, once the realm of fat clients, are now available to thin, browser-based clients thanks to advances in browser technology. The other approach, and the one at the core of this book, is an evolutionary step, where the delivery still uses the mechanisms of the thin client, including a declarative XML markup language named Extensible Application Markup Language (XAML) that defines the user interface, but has an incredibly powerful runtime supporting it. This runtime is the basis of WPF. It s a powerful rendering engine that can take the instructions passed to it from a server and render them richly. You ll see lots of examples of how to use WPF and XAML in this book. You ll use next-generation APIs for developing Windows applications version 3.0 of the .NET Framework, sometimes called WinFX or NetFX, as well as the new Windows software development kit (SDK). In the next section, you ll look at the components of this SDK and how they fit together.
