Are you looking for that NDP under current user or local machine?

local machine

And no NDP? Something went wrong there...
Are you able to reference framework 4.0 from a Visual Studio project?

i need c# code

Your tip is a bit outdated... :-(
For version 4 it shows .NET4.0 (no CLR) and 4.5 and onwards not shows at all...
