DotNetNuke was written in VB.NET, though the developer has shifted to C# since version 6.0. It is distributed under both a Community Edition MIT license and commercial proprietary licenses as the Professional and Enterprise Editions.
DNN Platform (formerly “DotNetNuke Community Edition” content management system) is open source software that is intended to allow management of websites without much technical knowledge, and to be extensible through a large number of third-party apps to provide functionality not included in the DNN core modules. Skins can be used to change the look of a website using DNN.
There are two commercial editions of the software with increased functionality compared to DNN Platform, and technical support. The DotNetNuke Professional Edition was introduced in February 2009 with version 4.9 and the most recent version 7.0 was released in December 2012. In July 2013, DotNetNuke Professional Edition was renamed Evoq Content. In addition, DotNetNuke Enterprise Edition was renamed Evoq Content: Enterprise.
