The .NET Framework provides extensive support for building international applications. Building an international application requires that the developer extract all of the aspects of the application that are specific to cultural conventions. Examples of culture-dependent information include language, number formatting, currency formatting, date and time formatting, and reading order (right-to-left, left-to-right). The code that is being developed should make no assumptions of a particular locale or cultural convention. Listing 18.1 looks at how not to develop an international application. The code for this localized application is available in the NotLocalizable directory.
