What is DotNetNuke?
DotNetNuke is the leading Web Content Management Platform for Microsoft .NET. DotNetNuke can be used as a web content management system (CMS) for simple web sites or as a powerful application development framework which enables businesses to quickly build and deploy feature-rich, interactive web sites and applications in Microsoft .NET.
An intuitive, menu-driven interface allows non-technical users to easily create new sites or extend the functionality and features of their existing web site when used as a web CMS. An open API and the availability of over 8,000 third-party add-ons available through Snowcovered.com allow web development professionals to create complex web sites for demanding applications. Installing new modules or skins is quick and easy, allowing users to deploy new functionality on their web sites in just minutes.
DotNetNuke is the world’s most widely adopted platform for building web solutions on Microsoft .NET. DotNetNuke powers over 600,000 portals, intranets, extranets, and public web sites. An enthusiastic open source community with more than 800,000 registered members supports the platform.
