qBic Open Source Platform
https://github.com/quintonn/QBic/qBic is powered by a code-driven configuration. The entire application is built using C# code. With qBic, you can create admin portals, dashboards, CMS sites, identity servers, and much more. All of this can be done while only writing .Net code, no HTML, JavaScript, or CSS. A lot of the magic is driven by abstract classes and inheritance.
