// Summary:
// .NET Framework (including Mono on Linux, macOS and WSL)
// - Set x509.PrivateKey works.

// .NET Core:
// - Set x509.PrivateKey for a .NET Core application FAILS.
// - PFX serialisation works on Windows.
// - PFX serialisation works on WSL and Linux.
// - PFX serialisation FAILS on macOS.
