A typed channel is similar to a Web service proxy object, which provides a typed object representation of the Web services WSDL interface. In a similar fashion, a WCF typed channel provides a typed object reference to a messaging endpoint and its associated operations. In order to create a typed channel, you need to first create the Web service and define its methods. This in turn defines a WSDL interface, which you can then extract automatically (for example, you can append WSDL to the Web service URI in order to review the WSDL document). Finally, you can use a code-generation tool to generate a proxy class based on the WSDL file. Today, we have a utility called wsdl.exe. WCF ships with an equivalent utility called WSDLgen.exe. The output of the code-generation utility is the typed channel, which provides a proxy representation of the WSDL interface as a managed object.

The search component handles this problem differently. Instead of responding to every keystroke made in the text box, once the user starts typing, an Ajax request is made at predefined intervals to update the results drop-down list, and then the Ajax request is made only if the contents of the text box have changed since the last time a request was issued.

An installed Drupal web site is a working prototype that you can add features to incrementally. Every enabled module adds a new piece of functionality. Sections and features should be developed incrementally, not all at once.

The Service Manager objects do all of the heavy lifting in processing messages and providing the support infrastructure for managing communications. Table 9-1 summarizes the important Service Manager objects and their purpose.

Building a Drupal site is different from building an HTML/CSS site in many aspects. Primarily, there is a clear distinction between content and markup. Because content is managed separately from graphics,

I ve found that it s much easier to create your content first and then build the theme around it. My recommendation is to configure as much of the site as possible before theming, with the goal of creating content, blocks, menus, and page views that can transfer between themes. When it comes time to theme, you then devote your time to arranging markup and displaying graphics using HTML and CSS. This logical distinction makes it easier to update graphics in the future by simply dropping a new theme in the themes folder. Practically speaking, this means a site takes on two different stages. In the first stage, I am simply adding content, arranging blocks, adding menu links, enabling modules, and more. Once I am finished with this stage, I have a blank site that has all the content and functionality but no graphics; it is simply white and black with some blue links (see Figure 3-1). Note that this site is using the Zen theme and not the default Garland theme.

Now that we ve shown you how easy Ajax can be, we hope you ll start using these techniques in your applications. In this chapter, we showed you a more involved example that illustrates some of the benefits of Ajax, and we discussed a number of resources you can use to further your understanding. By showing you some common patterns, we hope you ll see some places you can put Ajax to use for yourself, keeping in mind the common gotchas expressed in this chapter. Finally, frameworks such as Taconite can greatly simplify Ajax development work, and we think you ll agree they are worth using.
