1.24.1 nuget package is broken on linux

[ispysoftware]

Describe the issue

When we deploy our net 10 app to a linux x64 (ubuntu, glibc 2.35) target we get

The type initializer for 'Microsoft.ML.OnnxRuntime.NativeMethods' threw an exception. at Microsoft.ML.OnnxRuntime.SessionOptions..ctor()
at CoreLogic.AI.ONNX.ModelHelper.BuildOptions(Boolean useGPU)
at CoreLogic.AI.ONNX.ModelHelper.<>c__DisplayClass9_0.b__1()

RunDetect: Camera 1: Unable to load shared library 'onnxruntime.dll' or one of its dependencies. In order to help diagnose loading problems, consider using a tool like strace. If you're using glibc, consider setting the LD_DEBUG environment variable:
/home/sean/Desktop/Agent7200/onnxruntime.dll.so: cannot open shared object file: No such file or directory
/home/sean/Desktop/Agent7200/libonnxruntime.dll.so: cannot open shared object file: No such file or directory
/home/sean/Desktop/Agent7200/onnxruntime.dll: cannot open shared object file: No such file or directory
/home/sean/Desktop/Agent7200/libonnxruntime.dll: cannot open shared object file: No such file or directory

it looks like the managed wrapper is looking for a dll file on linux - not going to work

rolling back to 1.23.2 it works (segfaults, but that's another issue).
using the Microsoft.ML.OnnxRuntime nuget package

To reproduce

Try running an app using this nuget package on linux x64

Caused by #26415.

The PR description:

Linux/macOS: Native packaging may need updates to provide onnxruntime.dll in runtime folders (either as actual filename or symlink to libonnxruntime.so/libonnxruntime.dylib)

Please try symlink at the meantime.

Let me see whether we can provide a fix in next patch release.

I'll jump in here to say this is insane. An AI commit trying to fix a totally unrelated issue being released on an official version of the library without absolute any testing between October 2025 and now, breaking usage on both Linux and macOS, is beyond acceptable and not to the quality I expect from an official Microsoft library.

@titaiwangms @fs-eire @tianleiwu tagging you here because, while I'm all in for using AI to help development, this level of sloppiness and lack of concern on the impact of releasing slop is just absurd. This kind of nonsense (and Notepad being the target of a critical CVE) is just blowing all confidence we developers have on the Microsoft ecosystem.

I also suggest unlisting the v1.24.1 NuGet package to avoiding impacting more people with this broken release.

I think tis is also related, just win-x86 platform: #27362
