Does it work with SkiaSharp 3.0?

[elepner]

If I update SkiaSharp.HarfBuzz to the version 3.0.0-preview.5.4 along with SkiaSharp.NativeAssets.WebAssembly I get the error

Unhandled exception rendering component: The type initializer for 'SkiaSharp.SKObject' threw an exception.
System.TypeInitializationException: The type initializer for 'SkiaSharp.SKObject' threw an exception.
 ---> System.InvalidOperationException: The version of the native libSkiaSharp library (116.0) is incompatible with this version of SkiaSharp. Supported versions of the native libSkiaSharp library are in the range [88.1, 89.0).

I have given a try to run this in .net9 with no success. There's another error which appears even in Debug mode.

This may be fixed with #3064

Can you try the nightly on the preview feed: 3.118.0-nightly.27

https://aka.ms/skiasharp-eap/index.json

Let me know if this fixes it and I will push out the 3.x release.

EDIT: I see my fix was in the Blazor package, so will not reach your project. I got a PR to fix it in all the WASM things.

A fix for you now with the nightly will be to just install the Blazor package. I hope to have that fix merged ASAP.
