I've not removed this class because I was not able to test it on Full Framework because I can't even load the sqlite itself on Full Framework (not the extension):

Huh... OK...

I'm hoping this is somehow related to the test environment/xunit... Can I ask you to do a quick test from a full framework console program, with Microsoft.Data.Sqlite and the new nuget package, to make sure it actually works for users? Otherwise we might have an actual issue here (we specifically worked on making the nuget on full framework, but I no longer remember the exact details...)
