By default, Windows 2012/R2 does not include .NET Framework 3.5 in its local servicing store. Using Server Manager it can be installed using the original media by specifying the source (usually D:\sources\sxs). Alternatively, it can be installed by downloading directly from Windows Update:
- Open an elevated command prompt.
