Visual Web GUI

Visual Web GUI is a solution that allows you to write a winforms application and at compile time transform it into an ASP.NET application. The application has same look and feel as winforms applications and it will behave exactly as the winforms application does. So instead of creating an ASP.NET page you create a VWG-form. At Build time the form and controls are translated into ASP.NET, Ajax and JavaScript code.

I’m speechless. The whole thing is so amazing that you must see it before you believe it. Take a look at it.

And the whole stuff is open source and licensed under LGPL.
