Summary of PR:

  • Added usage of LibraryImport when targeting net7.0
  • Marshall environment name string as UTF-8 with the LibraryImport options
  • Using nint throughout over previous IntPtr
  • File-scoped namespaces
  • Fixed test being excluded on Linux for using environment from multi-process
  • Corrected numerous inconsistencies and analysis warnings where it made sense

Are there other language features this library would benefit from that I missed?

I'm going to run the benchmarks out of curiosity to see the differences between net6.0, net7.0 (master), and net7.0 (net7-csharp-improvements)
