The .NET platform is Microsoft's new computing platform designed to simplify development in the distributed environment of the Internet. Unlike many past initiatives of this type, .NET arrives with a rich set of classes and a programming paradigm designed to facilitate development that meets worldwide requirements. In this presentation, an overview of the internationalization support in .NET is provided along with several client and web demonstrations developed using C# as the programming language. Emphasis will be on the vital role that Unicode plays in .NET along with a discussion of the members of the Globalization namespace including language and regional information, calendars, common formats (dates, times, numbers, currencies, and percentages), textual analysis, collation, and separation of code and user interface data in both client and web applications.
