WebMatrix includes everything you need for open-source web development. Many of our developers rely on open-source software, so we worked with open source communities, developers, and standards groups to more tightly integrate functionality. You can build off of applications like Umbraco or Joomla, create a site from built-in templates, or start from scratch.
Joomla is a free, open source content management system and application framework that powers many web sites, built using PHP and MySQL. It’s easy to use on Windows, and WebMatrix makes it even easier.
In this video you’ll see how, in just a few minutes you can install a Joomla! site and start configuring it, including modifying the theme and adding content to the CMS.
