Does SkiaSharp work with Wasi Console Apps (WASM)?

[enghch]

I have a Wasi Console App (.NET 9, preview 6) which compiles to a single .wasm file. I can add nuget references to SkiaSharp and the SkiaSharp.NativeAssets,WebAssembly and it appears to compile file. But when I try to call Skia methods from my code, I get a DllNotFoundException for libSkiaSharp.

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

SkiaSharp is supported in Blazor Wasm so I assumed it would work in Wasi Wasm. Is there some extra build step I need to add to get the native assets statically linked into my wasm file?

SkiaSharp is supported in Blazor Wasm

Have you tested this in Blazor, yourself?

See this open SkiaSharp / Blazor Wasm issue.

It links to a closed issue, which contains a comment with a code snippet that might be relevant.:
#3037 (comment)

Perhaps this line:

<NativeFileReference Include="$(SkiaSharpStaticLibraryPath)\3.1.56\st\*.a" />

You could follow the steps (and these issues); get SkiaSharp working with Blazor Wasm. Then compare the resulting csproj to yours.

Not WASI, but a blazor-less WASM sample: https://github.com/mono/SkiaSharp/tree/main/samples/Basic/BrowserWebAssembly

Let us know if you manage to get it all working!

SkiaSharp and Blazor Wasm has never worked for me :'(

Are you able to open a new issue with this? I am pretty sure I fixed all of the .NET 9 issues in the last few releases. But, maybe I missed something.

[tossnet]

ok if you want I create new issue .
I was just testing your sample here https://github.com/mono/SkiaSharp/blob/main/samples/Basic/BlazorWebAssembly/SkiaSharpSample/SkiaSharpSample.csproj but the problem with this example is that it's not autonomous and depends on many other sources (<Import Project=”..\..\..\..\..\)
