3.5 is approaching end of life in the next few years, you definitely should not building anything new with it. There's a lot of QoL changes in modern .NET that makes your life as a developer significantly nicer. Even for building windows services, the modern Generic Host model is orders of magnitude better than anything in .NET Framework.

I'm shocked that 3.5 is still supported, it came out in 2007!
