Ultimately, it will not hurt any users if you target the Client Profile. This is because the client profile is a subset of the .net framework v3.5 sp1, and if v3.5 sp1 is already installed you don't need to install anything.
You can convert your managed applications to pure machine code using tools such as http://www.xenocode.com/ or http://www.remotesoft.com/linker/ so you won't need any . NET framework on the client machines at all.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
