Nuget packages after 172.52.0 do not support netstandard2.0

I tried using the most recent version (172.64.0 at time of writing) in a netstandard2.0 project, and it failed to restore. I suspect that's because 172.64.0 doesn't explicitly support netstandard2.0.

Version 172.52.0 is the newest version that works. Was removing support in later versions deliberate? If it was, what is the intended way forward for people using SMO in netstandard projects? If it wasn't deliberate, is there any chance of getting a new version out that does support it (even if it's just versioned as 172.64.1 or 172.64.0-netstandard or something, with no changes from the current 172.64.0)?

I don't think there's any particular bits in 172.64 that I need right now, so using 172.52 isn't a showstopper, but I do like to keep my references up-to-date as far as I can.

Compara los metadatos de NuGet y los frameworks de destino de las versiones 172.52.0 y 172.64.0, y después reproduce la restauración en un proyecto netstandard2.0. Se considera completado confirmar si la compatibilidad se eliminó intencionadamente y restaurar la compatibilidad con netstandard2.0 en un paquete posterior o documentar el procedimiento previsto para los usuarios afectados.
