Microsoft WebMatrix

From Microsoft: Microsoft WebMatrix makes it easy for anyone to create a new web site. Start from a built-in template or one of the free popular open source web applications, such as WordPress, Joomla, DotNetuke or Orchard, located in the online Web Applications Gallery. Customize your site using HTML, CSS, JavaScript, and other web standards. With WebMatrix you can use ASP.NET Web Pages including a new easy-to-learn programming model called 'Razor', or you can also use PHP or classic ASP. Publish your site and databases to your hosting provider or choose from a gallery of hosting providers that are compatible with the web site you build.
