This software is a web server written for the Microsoft® .NET.Framework. It can be used to host ASP.NET 2.0 and 1.1 applications. The server is an alternative to IIS, and can even be used on home PCs and office desktops. Its advantage is that it can easily be distributed with any ASP.NET application.

Cassini Web Server is in fact a Windows service. This service is installed during the setup process. It can be started, stopped, or restarted later either by using Administrative Tools -> Services in Control Panel, or by using the shortcut, which is placed in your Windows Start menu. The web server has a simple administration interface. You can use this interface (web page) to register new ASP.NET applications, or to edit the existing ones. You can specify a few details of the ASP.NET application, like its location on your hard disk, its default document, and a name that is used to identify it.

Applications distributed along with UltiDev Cassini can register themselves with the Cassini server after the installation. You don’t have to write code to accomplish this. If you need to redistribute advanced applications or applications that need extra configuring, a simple configuration API, written in .NET, is available.
