DNN Developer?
If you're a DotNetNuke Developer and are looking for Modules, you'll want to check out our DotNetNuke Modules page.

DNN (aka DotNetNuke) is an advanced content management system (CMS) specifically designed for websites, Intranet deployments, and web application development. Administrators are given complete control of their content, layout, security and membership and are provided with a powerful set of tools to maintain a dynamic and interactive site.

As an active member of the DNN open-source community, Efficion devotes a great deal of effort in contributing time and modules for the improvement of the DNN software and community as a whole.

Through the combined efforts of the DNN community, we have created a software framework that is reliable, flexible, and most of all, a powerful solution for meeting the needs of many different types of organizations. Learn More...

DNN Consultants with years of Experience

Back in 2004, when Efficion was just starting up and open source Content Management Systems were a fairly new concept, Efficion performed an exhaustive evaluation of the most popular CMS's in order to choose the best to build our business around. We chose DotNetNuke.

Built on top of the wonderful ASP.NET framework, it was technically superior, had a great community, a growing ecosystem, excellent leadership, had a great, extensible architecture, and was a very solid product. To this day, I feel strongly we made the right choice.

Since then, we've built the majority of our websites, intranets, and web applications on top of DNN. We offer a full range of services. Visit our services page to learn more.

DotNetNuke and MySQL

A question that I see a lot of is, "Can DotNetNuke run on top of MySQL?" The short answer: while It is possible, it is a terrible idea. The same answer is also true for Oracle. But that doesn't mean you can't write DotNetNuke modules that consume data from MySQL, Oracle, or any external data source.

The Long Answer

While DNN does provide a data abstraction layer so that it can, in theory, be run on top of any modern DBMS, the reality is DNN is a very large and complicated system that relies heavily on SQL Server specific Stored Procedures. The SQL used for DotNetNuke is chock full of Stored Procedures. The Stored Procedures improve the performance and security of the system.

A few intrepid souls have attempted to create and maintain MySQL providers but, with the availability of cheap hosting and free versions of SQL Server, there simply isn't enough need for that in order to make it worthwhile and those providers are long out of date.

Even if someone does manage get the latest version of DNN's core running against MySQL, it's still a bad idea because you would lose the key thing that makes DNN special, Modules. You would need to ensure that every module you ever want to use has a MySQL provider and that that provider would continue to be updated throughout the life of the module. Or, you would have to create a MySQL provider for every module that you want to use. The cost of doing this would far exceed the cost of using a hosting company that would provide you a shared SQL Server on which you can run DNN.

But don't lose hope...

DotNetNuke and IIS7 Integrated Pipeline Vs. Classic Mode

When I first started trying to install DNN on a local Vista installation I had various strange errors that I eventually determined to be due to the fact that I was running my IIS7 App Pool in Integrated Pipeline mode instead of Classic (IIS 6). And so, from that I learned DNN can't run in Integrated Pipeline more.

Today, I discovered that DotNetNuke can run in integrated pipeline mode as long as you're running DNN version 4.8 or greater. Charles Nurse discusses this in this blog.

DotNetNuke: Which modules are being used (and which aren't)

Sometimes, you need (or want) to know which of the modules that are installed on your DNN site are being used, which aren't, and where a module is being used. This can be useful if you want to uninstall unused modules for performance improvements or if you're planning on upgrading your site and you need to know what modules you'll need to test or upgrade. Here's some sql that will help you answer these questions...

Improving Your DotNetNuke sitemap

 There's an interesting article on a fairly simple way to improve the sitemap that DotNetNuke generates for you. It doesn't require any core modifications but does set page priority up in a way that makes a lot of sense while also not requiring much work.

DotNetNuke Corporation raises funding through venture capital

The for profit wing of DotNetNuke, the DotNetNuke Corporation, announced an infusion of funding today from a couple venture captical firms. As someone who's livelihood is intricately tied to DNN, I've got mixed feelings about this news. While I fully appreciate that the new funding should help take DotNetNuke to the next level, both from a features and functionality as well as a marketing and penetration perspective, it also worries me that priorities may shift, revenue may trump the "common good", and everything may get more profit minded and expensive. So, we'll just have to wait and see...
