• install .NET 7

• install Rust and wasm-pack

• Optionally, install Node.js & npm in order to run package.json script

npm run run

dotnet tool restore
dotnet fable FableRustRaytracer/FableRustRaytracer.fsproj --lang rust --outDir FableRustRaytracer/
# this throws an error, but it's safe to ignore
# ./FableRustRaytracer/RayTracer.fs(157,34): (157,69) error FABLE: System.Double.Pow is not supported by Fable
wasm-pack build FableRustRaytracer/ --target nodejs
dotnet run --project WasiFableRaytracerFSharpAvalonia/WasiFableRaytracerFSharpAvalonia.fsproj

Because why not. An example use case for this may be some existing WASM code that you want to use in your desktop app or for example some .NET code that performs better when compiled to Rust and then WASM.
