1. DotNetNuke

DotNetNuke is considered to be one of the most popular ASP.NET CMS systems around. It currently has more than 1 million users (including all four editions). The free edition is known as the Community Edition. The commercial options include: DotNetNuke Professional, Elite, and Elite Premier. It is known for being extremely flexible because it uses open API's which allows for easy integration with other applications.

It features 25 standard modules as well as a large number of commercial modules as well. From an administrative standpoint, DNN stands out because the administrator can support multiple websites from one location. The more websites you have, the more important this feature is. In the area of support, it is important to understand that the Community version has no official support available, however there are a variety of support forums with a very active DNN community. With the paid versions, there are different levels of support available. In total, DNN has built a strong community and consistently proves itself to be a strong option.

2. Orchard

The Orchard CMS is still very young. While it is still in the development stage, it was launched early to help create greater participation from the development community. It is an open sourced project that is completely free and is being designed to create reusable components using the ASP.NET framework. The goal of the shared, reusable components is to serve as a basis for new extensions and applications on an ongoing basis.

Currently, the Orchard Project has clearly identified 3 goals that it wants to pursue. First, they want to create individual applications that will appeal to not only end-users, but also developers and scripters. Second, they want to develop a large base of reusable components that can act as the base of all 3rd party components. Finally, they want to create a large and active community to help define and create these applications. The Orchard CMS is still a ways off from being stable and widely used, however it is worth keeping an eye on. If it actually achieves all of its goals, it could prove to be a very powerful CMS option.

3. Kentico
 

Kentico offers a variety of different licenses. The free license offers limited features compared the commercial licenses, and you must keep the Kentico logo and link in the footer of your website (for the free version only). Depending on what type of license you need there are a variety of packages available. A license for 1 website will range from $1999 to $14,499, for 1 server (up to 10 websites) it is $5999 to $23,499, and for 1 server (unlimited websites) it is $9999 to $32,499. Additionally, prepaid consulting services are $1000 for 10 consulting credits (1 credit = 30 minutes).

The biggest benefit of Kentico is that it was designed to be very easy to use for non-technical users, while still allowing for rapid site development. Kentico is a complete solution, which means that there is no need to purchase additional software or 3rd part components. It can also be fully customized as the source code is available with certain licenses.
