Nostalgia .NET - WinEvent
Component for tracking low-level system-wide events
"The Microsoft Windows operating system includes a feature, called WinEvents, that enables processes and applications running on the Windows desktop to exchange certain types of information. Accessibility tools that use Microsoft UI Automation and Microsoft Active Accessibility are among the primary users of the WinEvents.
In the context of accessibility, UI Automation providers and Microsoft Active Accessibility servers use WinEvents to notify clients of changes in an application UI, such as when a UI element has been created or destroyed, or when an element name, state, or value has changed."
(From MSDN)
WinEvent is very powerful, but unappreciated, so, for instance, we can found using of the system-wide hook for tracking the mouse position, but there is no examples of WinEvent using for the same purpose. WinEvent can, for example, track the mouse cursor changes throughout the system, report changing of size and position of any window in the system, track switching active windows and much more. Of course, native Win32 way is not most simple and convenient, but Nostalgia .Net has special WinEvent component that allows to have all the power of WinEvent and to have no problems with coding at the same time.

In addition to events Nostalgia .Net declares special enum types for using instead of Win32's constants in event handlers, so you don't need to use numeric constants even in handler of raw WinEventHook event.
Just activate component at runtime from your code and enjoy:
winEvent.Active = true;
As you can see in the demo source codes, you need only several lines of native C# code to access all the power of WinEvent.
