TaskDialog.NET component provides classes .NET developers can use to add Vista-style task dialogs to their .NET applications that will work on any platform supported by the .NET Framework. Developers simply use TaskDialog class in their code to construct task dialogs as needed and when showing the task dialog the TaskDialog.NET will either use native task dialog API if available (on Windows Vista or higher) or use standard .NET classes to construct task dialog with the same look and feel as the native task dialog on operating systems prior to Windows Vista (Windows XP for example).
