DotNetNuke ( DNN ) is a free web application framework based on the ASP.NET platform .


In one installation of DotNetNuke, multiple portals with independent access authorizations, individual design, languages ​​and content can be created by one host and managed by the administrators who have been set up. For this purpose, the administrators and editors have numerous features and tools at their disposal, such as:

The functional scope of the system is implemented by modules that represent encapsulated applications
enables individual structure of the pages, separating the content from its visual representation
Drag and drop
Containers and modules can be placed within the pages with the mouse using the drag-and-drop functionality
File management
Files can be uploaded to the portal and made available
waste paper bin
Deletion and restoration of deleted content, modules and pages
Event log
Overview of user logins and errors that have occurred as well as critical actions
Language editor
Creation of translations
Client callbacks simplify handling and can be integrated into your own modules (Microsoft AJAX and jQuery are integrated).

DotNetNuke can be individually adapted to the respective user requirements and has versatile interfaces that enable communication with other systems in the IT landscape. In addition to the built-in login service, OpenID , LiveID , Cardspace and Active Directory can be used for authentication . Secure communication via SSL is supported as standard and can be activated individually for each side. In addition, it is possible to integrate further, self-developed, authentication providers into the portal.

Languages ​​and multilingualism

By default, DotNetNuke is delivered in English (en-US). The translation can be implemented using numerous language packages available, including German, with more than 700 German language packages being provided free of charge by the user group. Multilingual content (menu, texts, etc.) can be implemented with various additional components.

DotNetNuke now also supports multilingualism on the system side. However, the functionality currently still contains some weaknesses.

Runtime environment and license

DotNetNuke is based on the current Microsoft ASP.NET technology (programmed in C # ) and was made freely available as the largest open source project on this platform under a modified BSD license by project founder Shaun Walker. The copyright holder is DotNetNuke Corp. In addition, DotNetNuke Corp. Versions licensed in the USA are available, which also contain extended support in the various expansion stages. The company has now also opened an office for Europe. This is located in Amsterdam and currently looks after the entire European area.

Development in recent years

Since the first version was released on December 24, 2002, DotNetNuke has quickly gained users - especially in the English-speaking world. Commercial portal solutions from Germany are partly based on an adapted DotNetNuke. DNN has been part of the Web Site Starters for Windows since May 2005 and is listed in the Microsoft Web Application Gallery . Since 2007, the DotNetNuke conferences annually Open Force in Europe and the United States held in 2010 was the first time the European Day of DotNetNuke organized. A user group organizes all-day specialist events for German-speaking countries.

Cooperation with other frameworks

  • JavaScript frameworks: Version 4 of DotNetNuke uses its own JavaScript framework, which was replaced by jQuery in version 5 - also because Microsoft preferred jQuery as the JavaScript framework at the time.
  • AJAX.Net The AJAX solution from Microsoft is supported, with an update panel being used automatically if required.
  • CSS Frameworks: No specific framework is currently recommended. YAML ( YAML website ) is currently the only framework with support in the DotNetNuke community , among other things because YAML harmonizes with jQuery.
  • Telerik Web Controls are delivered with DotNetNuke from version 5.2.
