Roadkill .NET is a lightweight but powerful Wiki platform built on the following foundations:
- .NET 4.5
- ASP.NET MVC 5 with Razor
- Lucene.net search engine
- Creole, Media Wiki and Markdown syntax support
- Bootstrap 3 based UI.
- Supports SQL Server, SQL Server CE, SQL Azure (v1.6+), Sqlite, MySQL, Postgres, MongoDB
- It's themeable and extendable, has documentation, supports Active Directory authentication and is (I hope) extremely easy to use. It's Free Open Source (FOSS)
Roadkill is licensed under the MS-PL license which means it's free to use commercially or privately, but requires you to retain the copyright, trademark and attribution if you intend to distribute it (typically for commercial gain).
