c# - parameter - Javascript Like Modal Window para WinForms

ejecutar funcion javascript desde codebehind c#

Question

¿Alguien conoce un buen control de Ventana Modal como los que se usan en Javascript pero disponible para WinForms (C #) con el fondo transparente y todo eso?

Ejemplo en Javascript http://okonet.ru/projects/modalbox/

Algo como

ModalCoolForm f = new ModalCoolForm();
f.ShowDialog(this);
