Code

try 
{ 
    using (SKBitmap bitmap = new SKBitmap(500, 500, SKImageInfo.PlatformColorType, SKAlphaType.Premul)) 
    { 
        using (SKSurface sKSurface = SKSurface.Create(bitmap.Info)) 
        { 
            SKCanvas sKCanvas = sKSurface.Canvas; 
            SKPaint sKPaint = new SKPaint(); 
            sKPaint.Color = new SKColor(255, 0, 0); 
            sKCanvas.DrawText("Blazor", new SKPoint(250, 250), sKPaint); 
            MemoryStream stream = new MemoryStream(); 
            sKSurface.Snapshot().Encode(SKEncodedImageFormat.Png, 100).SaveTo(stream); 
        } 
    } 
} 
catch (Exception ex)

I was able to run your code after adding SkiaSharp.Views.Blazor package. https://www.nuget.org/packages/SkiaSharp.Views.Blazor/2.88.7. I'm using WASM .NET 8.0 Visual Studio 2022 version 17.9.1.

You need to either install SkiaSharp.Views.Blazor or SkiaSharp.NativeAssets.WebAssembly in order to get the binaries for WASM.

Try the latest versions as we have also fixed several packaging issues.

SkiaSharp.Views.Blazor

I'm getting the same issue. I tried the latest release and the latest preview release.

I found a thread from a few years ago #1725

Doing this is a work-around:

	<ItemGroup>
		<NativeFileReference Include="$(HarfBuzzSharpStaticLibraryPath)\8.3.1-preview.1.2\*.a" />
	</ItemGroup>
