Orchard CMS, a free open-source content management system running on IIS7, .NET Framework 4.0, and ASP.NET MVC 3.0. I've kept things clean and simple, but the website does host a custom Orchard Theme as well as a number of Orchard customizations.
Orchard CMS Runs on free SQL CE Database
There is paying no extra charges from your host provider for a SQL Server Database for Orchard. Orchard CMS runs on the free SQL CE 4 Database from Microsoft that is automatically created by Orchard on installation and managed by Orchard during the lifetime of your website. SQL CE can also be copied to and from the website like any other file so you also don't need to install or purchase any expensive or complicated tools for backup or moving your website and database to another host provider. If you do choose to upgrade your database to SQL Server Express or SQL Server 2008 R2, this can be done fairly easily when appropriate. Since most of my clients run Orchard CMS with the free SQL CE Database from Microsoft.
Orchard Theme for custom Websites
The key to to Orchard Website is the Orchard Theme, which defines the look and user experience of your Orchard Website. Orchard comes with a built-in theme, called The Theme Machine, or one can choose a free theme from the Orchard Gallery. As more and more Orchard Web Designers enter the Orchard Community the choices of Orchard Themes will increase and improve, but in general, the theme choices right now in the Orchard Gallery are not that great.
