Open source maintainer here. Strong Naming is a thing of the past. For .Net (4.x) you should release a specific build.
This driver will break all the modern .net ecosystem, mongo will be left behind.
From ms doc about SN:
For .NET Core and .NET 5+, strong-named assemblies do not provide material benefits. The runtime never validates the strong-name signature, nor does it use the strong-name for assembly binding.
Strong-names are left over from previous eras of .NET
Don’t be like IE, be like MongoDB.
