Microsoft has just released the latest version of their Web Platform Installer and Web Application Gallery.
The beta for version 2 has been out since March, adding a community version of PHP and ASP.NET MVC 1 to an already full list of applications. New web applications that could be downloaded included Umbraco and Silverstripe Web CMS.
With today's release of the WPI, you will also get the Windows Azure SDK to get you started on those cloud-based applications and the IIS Media Pack.
If you were nervous about installing the beta version of WPI 2, you don't have to wait any longer. This is definitely an easy way to get your development environment up and running and a version of your favorite open source Web CMS to start developing your web applications.
