Visual WebGui is a new AJAX framework that took a different approach to web application development, specially designed to simplify building highly complex applications like Outlook Web Access (OWA). Visual WebGui makes it possible for developers to create web applications by using full WinForms server side API that includes design-time capabilities. By adopting the WinForms object module and development concepts Visual WebGui has completely simplified the development of web applications. Alowing you to program as a VB/WinForms programmer and not as a web programmer makes much more sense when developing web applications like Outlook Web Access.

In pratica si sceglie un tipo di progetto apposito. Si usano i controlli di VisualWebGUI che vengono draggati su di una Windows Form: appena si fa partire il progetto, si apre invece un Internet Explorer e mostra un'applicazione web con il look&feel è quello di una windows application.
