Support for Windows Arm64

[yassinebennani]

Hello,

I could not find a win-arm64 target runtime, is there any plan to support it ?

I forked Sodium.Core repo but I ended with PlatformNotSupportedException

System.PlatformNotSupportedException : Could not initialize platform-specific components. libsodium-core may not be supported on this platform. See https://github.com/ektrah/libsodium-core/blob/master/INSTALL.md for more information.
----> System.DllNotFoundException : Unable to load DLL 'libsodium' or one of its dependencies: The specified module could not be found. (0x8007007E)

Thank you

It's been supported for a long time, and continuously tested in CI.

Just use Zig:

zig build -Doptimize=ReleaseFast -Dtarget=aarch64-windows

The only reason why it's not included in the Nugget package is that nobody ever confirmed that this actually works.

For what it's worth, we run libsodium on aarch64-windows quite happily (but obviously have to build and then package it ourselves since it's not in the nuget package).
