[BUG] DllNotFoundException when trying to invoke Skia in a Wasi Wasm Console app

[enghch]

Description

When trying to run a Wasi Console app that depends on SkiaSharp. It builds the single-file wasm just fine. I added the nuget package for the NativeAssets.WebAssembly. But when attempting to run, it throws:

"System.TypeInitializationException: TypeInitialization_Type, SkiaSharp.SKImageInfo --- System.DllNotFoundException: libSkiaSharp at SkiaSharp.SKImageInfo..cctor()

The NativeAssets has build targets for Blazor, but seems to be missing them for Wasi Wasm apps.

I'm on .NET 9 preview 6. Is there some workaround or something I'm missing? I attached a small repro project. I included the wasm file in case that's useful. If you're not familiar with wasi or wasitime, see in the instructions in the readme.

Hi @enghch , I have a similar issue in Unity (see #3016 ) Do you think it's linked ?

[enghch]

Hmm! Good question. I was assuming the issue for me was because the NativeAssets package didn't include targets for wasi wasm. But maybe it's a larger issue with SkiaSharp in general?

The 3.x series should be including the native assets. Have you tried that yet?
