While playing with the new Windows Server 2012 and Windows 8 Client I found out that the .Net Framework 3.5 SP1 option was grey out and not available. After doing some digging and reading several forum I found the answer.
Steps to enable .Net Framework 3.5 SP1 in Windows Server 2012
1. Open a Command Prompt with Administrator Priveledges
2. type: dism /online /enable-feature /all /featurename:netfx3 /source:d:sourcessxs /limitaccess
Worked for me, thanks
The GUI options would be to go through Server Manager -> Local Server -> Roles and Features -> Tasks -> Add Roles and Features -> Next -> Next -> Next -> Next -> Select .NET Framekwork 3.5 Features -> Install
When you go thru the GUI, it ask for the source of the files and if you do not have the source it is a pain. This way you can just add it to your build process. 🙂
so for the gui, what path do i use for a source? I cant believe Micro$oft would not put in a link. (Ok, i guess i can, they never do anything the right way.)
