WebMatrix is a free Web development downloadable toolkit that installs in minutes and elegantly brings together a Web server, a database, and programming frameworks into a single, integrated experience.
WebMatrix lets you code, test, and deploy both ASP.NET and PHP applications side by side.
WebMatrix provides inside the toolkit a world of popular and free open-source Web applications, including DotNetNuke, Umbraco, WordPress, Joomla!, and more.
Simply select which application you want from the built-in gallery, and WebMatrix handles the downloading and installation of your new Web site on your web server.
WebMatrix can also be used to find a Web host that fits your requirements and which can use the built-in publishing support for FTP, FTPS, and WebDeploy.
WebMatrix includes a small, embedded database called SQL Server Compact that can live with your Web site code and content. Use it to start building your next Web site, and when you’re ready to publish, just copy the database file from your computer to any Web server and it will run— no extra installation required.
The days of hand-editing configuration files and making sure you have all the right components are long gone.
WebMatrix is free.
