Package target framework should include net472 and not net48

[catester]

I see that you use <TargetFrameworks>net8.0;net48</TargetFrameworks> but do you use anything special from net48 because that framework is not much different than net472 ?
net472 is a good base (a cornerstone with real netstandard2.0 support etc.) for legacy projects so I recommend you use <TargetFrameworks>net8.0;net472</TargetFrameworks> instead.
