Description

Stack trace:

System.TypeInitializationException: The type initializer for 'SkiaSharp.SKImageInfo' threw an exception. ---> System.DllNotFoundException: libSkiaSharp at SkiaSharp.SKImageInfo..cctor()

Note: When trying the same approach in Blazor WASM .NET 6.0, there is no issues.

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.
