WebMatrix was recently released and helps make creating websites super easy. WebMatrix is everything you need to build Web sites using Windows. It includes IIS Developer Express (a development Web server), ASP.NET (a Web framework), and SQL Server Compact (an embedded database). It streamlines Web site development and makes it easy to start Web sites from popular open-source apps. The skills and code you develop with WebMatrix transition seamlessly to Visual Studio and SQL Server.
All you do is create the application, click publish, and a fully functional site is up and working. How it runs on your local computer is how it will run on the website!
What is even cooler is it connects you to a world of popular and free open-source Web applications, including DotNetNuke, Umbraco, WordPress, Joomla!, and more!
