Package not compatible with .net6

[nibraso]

I get this warning Package 'Two10.CountryLookup 1.0.4' was restored using '.NETFramework,Version=v4.6.1, .NETFramework,Version=v4.6.2, .NETFramework,Version=v4.7, .NETFramework,Version=v4.7.1, .NETFramework,Version=v4.7.2, .NETFramework,Version=v4.8' instead of the project target framework 'net6.0'. This package may not be fully compatible with your project.
I ask myself if there is a solution to go around this warning!
