TaskDialog.NET

Add Vista-style Task Dialog to .NET applications on any platform supported by the .NET Framework. Task dialogs enable developers to create well-designed, consistent dialogs boxes efficiently and it is a versatile alternative to the old message box which has often been used to create dialog boxes that are difficult to understand and use.
There are no standard classes in .NET framework to work with task dialogs and in order to work with task dialogs on Windows Vista operating system .NET developers needed to work directly with the task dialog API (unmanaged code) that is provided with Windows Vista operating system.
Applications written for .NET framework are supposed to work on every platform (operating system) that is supported by the .NET framework. Since task dialogs were introduced with Windows Vista there was obviously a problem what to do when an application is run on other operating systems like Windows XP for example.
The 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).
All task dialog features available through TaskDialog.NET classes work exactly the same no matter whether a task dialog is currently using native API support or standard .NET classes to operate. This saves a lot of effort and time for developers and allows you to start using task dialogs in your .NET applications within minutes.
