[chaojian-zhang]

System Information (please complete the following information):

• OS & Version: Windows 10
• ML.NET Version: ML.NET v4.0.2
• .NET Version: .NET 8.0

Describe the bug

In https://github.com/dotnet/machinelearning-samples, open ObjectDetection project, explicitly depend on SkiaSharp package 3.116.1, run, and observe failure:

========= End of Process..Hit any Key ========

Root cause is ImageAnalytics.

To Reproduce
Steps to reproduce the behavior:

1. Download and use https://github.com/dotnet/machinelearning-samples
2. Open samples\csharp\getting-started\DeepLearning_ObjectDetection_Onnx\ObjectDetectionConsoleApp.ObjectDetection.csproj
3. Use NuGet to explicitly install SkiaSharp version 3.116.1
4. Run
5. Fail

Expected behavior

Shouldn't fail or are there alternatively/ways to configure?
Also the package dependency of ML.Net.ImageAnalytics claims SkiaSharp >2.88

Screenshots, Code, Sample Projects
See log error above.

Additional context
I am using ML.Net in a project that already depends on SkiaSharp explicitly.

The method was tagged as a breaking change (method removed) in 3.0:
https://github.com/mono/SkiaSharp/blob/3dcd422df6afe0790f2dc7911a86f5107a6a5fbd/changelogs/SkiaSharp/3.0.0/SkiaSharp.breaking.md?plain=1#L96

Rather the ReadOnlySpan was replaced by Span in this commit:
mono/SkiaSharp@a140a20#diff-2fe5c8811697b2372f41ceac4dec6242de61cddbc98e636348fdab5b3b0ee175L369

And remains in the current main:
https://github.com/mono/SkiaSharp/blob/cf545baf112b0eecb3ea4e3b9dda38e664f63054/binding/SkiaSharp/SKBitmap.cs#L300

So essentially we need to get the version of SkiaSharp updated.
