Installing .Net 3.5 onto Windows 8 and 8.1 using DISM
This is one of those posts to save me searching the web every time I need to install .Net 3.5 on a Windows 8 (and now 8.1) system. If the automated installation via add/remove features fails then you need the correct DISM command.
For those who have not yet encountered it, DISM allows you to perform actions on Windows image files in a process called Offline Servicing. However, it also allows you to perform the same functions online – on your current windows system.
