Get .NET SDK with sudo apt install dotnet9 (or dotnet-sdk-9.0), brew install dotnet for macOS
Get FSharpPacker tool with dotnet tool install -g --allow-roll-forward FSharpPacker
Make an F# interactive script file (e.g. copy the phash.fsx below)
Compile it with fspack {your-script.fsx} -f net9.0 -o {destination} --aot
(in this example: fspack phash.fsx -f net9.0 -o . --aot), note that it will take some time to do so for the first time - .NET needs to fetch IL AOT Compiler from Nuget
Profit! You have compiled an F# script to a native binary
(Optional) If you add fspk.fish, the process is simplified to fspk {my-script}.fsx!

Note 1: if you are not using macOS or FreeBSD, give https://github.com/ieviev/fflat a try which can produce even smaller binaries
