I would like to maximize StudyX's .NET compatibility, and make sure that nothing special has to be installed on Windows 8. I t looks like 3.5 is not available natively on Windows 8, but I am not sure about 4.0. Also, I could do 4.5 but I think that will cause more issues with Windows XP/7...

What version of .NET do you recommend?

I found a few resources:

PS: I hate how Microsoft makes it so hard to keep compatibility with all of their OSs. I guess they are trying to force upgrades.
