[BUG] Unable to load library 'libSkiaSharp'.

[jakobeazy]

Description

using svg.skia on anASP.NET website i get the following error:
Exception message: The type initializer for 'SkiaSharp.SKImageInfo' threw an exception.
Unable to load library 'libSkiaSharp'.

The strange thing is that debugging the code locally, it works, but when deploying it to a server it fails with this error.
The versions i an using:
Svg.Skia: 1.0.0.13
SkiaSharp: 2.88.6
SkiaSharp.HarfBuzz: 2.88.6
SkiaSharp.NativeAssets.macOS: 2.88.6
SkiaSharp.NativeAssets.Win32: 2.88.6

the project is a .NET Framework 4.7.2
I can't figure out why it can run locally and not remote.

The best way to share code for larger projects is a link to a GitHub repository: https://github.com/user/repo/tree/bug-123

But, you can also share a short block of code here:

// some C# code here

You can also share some XAML:

Is the libSkiaSharp.dll file in the bin folder somewhere? How are you publishing/deploying? Are you able to share a msbuild binlog so I can see why the native binary is not reaching the final output.

If you run the app locally after publishing, does it work?

@mattleibow We're also seeing this error but when trying out 3.0 preview 2.

It's a browser-wasm app on .Net 8. Loads fine on 2.88.7 and HarfBuzzSharp 7.3.0.1. We don't use Blazor but we do include reference to SkiaSharp.Views.Blazor for InterceptGLObject workaround and that's where it fails to load libSkiaSharp.

Haven't tried publishing yet as we're seeing this error with regular dotnet build.

Didn't want to bother early because it's still a preview. But can create a minimal repro if that's already expected to work properly.

hi
I was actually using the svg.skia nuget package. Changing to use the svg package solved it for me.

[prashants7718]

Hi @jakobeazy ,

How you have solved this issue, have you changed package and used another package for svg generation

[jakobeazy]

Yes, i changed the nuget package from svg.skia to svg.

[mattleibow]

@romansp it should be working since there should be no changes for wasm in 3.x Please attach a repro/sample so I can have a look.

@mattleibow I have the same issue when trying to run a Wasi Console app that depends on SkiaSharp. It builds the single-file wasm just fine. But when attempting to run, it throws:

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

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.
