As a Win7 user who had endless problems with .NET 3.5, and would prefer that he stay disconnected because he is corrupted, it doesn’t work anyway, and once in this state is not fixed in Win7 without a new, new installation of Windows, I want the programmers to simply NOT require its installation .. NET 4.1+ is compatible with versions 3.5.1 and if you write your code correctly, so that you are looking for functionality 3.5, not 3.5, it works, and if you encoded it correctly, you could just install 4.2 instead of 3.5 and this will work, but I have a small handful of programs, including all of your own MS mail applications (such as outlook), which simply insist on using .NET 3.5, and you know what? None of them work on my system.
I would also like to add that if I installed some piece of software that turned Windows features on or off on my system without first asking permission, you would receive a hate letter from me and that software would be disconnected from my as fast as I could remove it and delete it.
