Dotnet Installation on Windows 2012 R2
Many times I have seen people trying install dotnet 3.5 from download package and it fails. Because dotnet package can be installed only from Windows Source Files or using updates.
Install dotnet 3.5 from OS Media which is mounted under D: drive.
dism.exe /online /enable-feature /featurename:NetFX3 /Source:d:\sources\sxs /LimitAccess
