Npgsql, .net-version and OS-version

[FFF]

Got adventurous and installed Npgsql 6. Using this fails with a "missing System.Data.Common V5.0.0.0".
I suppose that might be connected with my trusty Win8.1/64 machine sitting on runtime version 4.5.50709 ?
If so, is there common advice what to do: using older npgsql, updating dotnet, if so, to which version?

Hi Karl,
I'm using an older Npgsl.dll (3.2.7) because newer ones have to many different dependencies that may conflict with other libraries.
