DotNetNuke(dnn)目前分為Professional和Communit兩個版本。我想很多人都有使用哪個版本的疑惑。

解答了這些疑惑，并且對DNN重新定義的商業模式做了解釋。DNN的商業模式被稱之為“Open Core.” 的模式，也就是說，DNN的核心部分是免費和開源，不管是Professional版本還是Community版本。并且這兩個版本的核心部分功能也是一樣的。
Nike Kalyan用這個圖解釋了什麼是DNN的核心：
那Professional版本和Community版本有什麼差別呢？通俗的講，兩個版本的差別就是釋出是附加的Extesion（也就是之前的Module）不同。
Communit版本會附加一些免費的子產品，像這樣：
而Professional版本則會增加一塊收費的Professional Extension

而Professional版本是面向對功能要求更強的商業需求，對安全、效率、電子商務和可擴充性都有增強。
下面這個表是兩個版本即将增加功能的詳細差別：
