.Net is powerful, but not all-powerful, so sometimes we need to use Win32 API for our .Net applications.

Nostalgia .Net offers several simple-to-use classes, and components that will allow you to forget about the headache of Win32 and just use the power of Win32 in your application the same way as you use the native.
