.Net 2 is not the default framework option … No, you get .Net 4. To change it, you select Project / <your project name> Properties / Compile / Advanced Compile Options, and select the Target Framework you want.
I prefer to use the .Net 2 Framework as it’s the lowest common denominator on the systems I write code for. And yes, I documented this, as I can’t remember where the option is, and Google Search wasn’t my friend at the time.
