DotNetNuke(dnn)目前分为Professional和Communit两个版本。我想很多人都有使用哪个版本的疑惑。
Nik Kalyani的两篇文章
DotNetNuke Business Model and Product Roadmap (Part 1 of 2)
DotNetNuke Business Model and Product Roadmap (Part 2 of 2)
解答了这些疑惑，并且对DNN重新定义的商业模式做了解释。DNN的商业模式被称之为“Open Core.” 的模式，也就是说，DNN的核心部分是免费和开源，不管是Professional版本还是Community版本。并且这两个版本的核心部分功能也是一样的。
Nike Kalyan用这个图解释了什么是DNN的核心：
那Professional版本和Community版本有什么区别呢？通俗的讲，两个版本的区别就是发布是附加的Extesion（也就是之前的Module）不同。
Communit版本会附加一些免费的模块，像这样：
而Professional版本则会增加一块收费的Professional Extension
而Professional版本是面向对功能要求更强的商业需求，对安全、效率、电子商务和可扩展性都有增强。
下面这个表是两个版本即将增加功能的详细区别：
