OrchardCMS/Orchard — reverse-engineered prompt

Build me a flexible content management system like Orchard, using ASP.NET MVC and .NET Framework. I want it to let site owners create and manage different kinds of content, like pages, blog posts, photos, products, and comments, without needing to hard code everything.

The main idea is that content should be made from reusable parts, so someone can compose new content types in the admin area. Please include a clean admin experience for managing content, themes, menus, users, and settings. I also want a module system so features can be added or replaced without changing the whole app, for example comments should be able to work on several content types.

Make it feel community friendly and extensible, with a simple default theme and enough sample content to test it. Keep the code organized so future developers can add modules and themes. Look up the current Orchard 1 docs online if you need guidance.
