[BUG] System.DllNotFoundException: libSkiaSharp when using SkiaSharp.Blazor.Views in Blazor WASM in .NET 9 RC2

[GokulprasathVenkatachalam]

Description

I created a new WASM project using SkiaSharp.Blazor.Views to utilize SKPath, but it throws an exception, preventing access to the SkiaSharp object.

My project references the following package:

      <PackageReference Include="SkiaSharp.Views.Blazor" Version="2.88.8" />

.NET 8:

default.NET8.mp4

.NET 8 Sample:
SkiaSharpNET8.zip

.NET 9:

default.NET9.mp4

.NET 9 Sample:
SkiaSharpNET9.zip

This issue only occurs in .NET 9; it worked perfectly in .NET 8. Could you please investigate this issue and provide suggestions?

Code

Code Snippet:
Home.razor

@page "/"
@using SkiaSharp;

<div>SkiaSharp NET 9</div>
@code {
    SKPath DrawingPath = new SKPath();
}

.NET9 Sample:
SkiaSharpNET9.zip

Expected Behavior

Ensure the sample runs without exceptions, similar to how it worked in .NET 8.

Actual Behavior

It throws a System.DllNotFoundException: libSkiaSharp exception.

Hi Team,

We have updated to the latest preview of 3.0.0-preview.5.3 in the early access NuGet feed and added the following codes in the .csproj file, which works fine with SkiaSharp access in Blazor WASM:

<PropertyGroup>
    <WasmNativeStrip>true</WasmNativeStrip>
    <WasmBuildNative>true</WasmBuildNative>
</PropertyGroup>

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

I have attached a sample for your reference. When can we expect the standard release for these changes on nuget.org? Given that .NET 9 is scheduled for release on November 12, is it possible to have this release on or before that date?

Sample:
SkiaSharpNET9.zip

Thank you.

Best regards,
