Downloading and Installing the .NET Framework 4.5.2，發佈日期：2014/5/6
.NET Framework 4.6.x的需求應該短期不會有，但還是準備一下
而.NET Framework 4.6才剛剛於2015/10/15發布，就旋即發布4.6.1，真的是!@#$
另外連微軟自家的Exchange Server 2016 RTM也僅支援.NET Framework 4.5.2，而不支援.NET Framework 4.6，這也是另一個窘事
連同Skype for Business Server 2015/Lync Server 2013，微軟也希望暫時不要安裝.NET Framework 4.6.1
官方說明：
.NET Framework 4.6.1 and Skype for Business Server 2015/Lync Server 2013

This is an offline installer. There are separate installers for web and offline installation. If you intend to redistribute either of these installers in the setup for your own product or application, we recommend that you choose the web installer because it is smaller and typically downloads faster. You can download the web installer here. Wherever possible, Microsoft recommends you use the Web Installer in lieu of the Offline Package for optimal efficiency and bandwidth requirements. The offline package can be used in situations where the web installer cannot be used due to lack of internet connectivity. This package is larger than the web installer and does not include the language packs. You can download and install the language packs from here.

The web installer is a small package (less than 1 MB) that automatically determines and downloads only the components applicable for a particular platform. The web installer also installs the language pack matching the language of the user’s operating system.
