The framework [.../onnxruntime.framework] is a framework of static libraries, and will not be copied to the app

Describe the bug

I've created a toy MAUI project and everything build and run well until I add and use the following dependencies:

    <PackageReference Include="Microsoft.ML.OnnxRuntime" Version="1.19.2" />
    <PackageReference Include="Microsoft.ML.OnnxRuntime.Managed" Version="1.19.2" />

Whenever I try to use a resource from the dependency, the app crashes (exception below).

The build generates the following warning that I assume is directly related:

warning MT7091: The framework obj/Debug/net8.0-ios/iossimulator-arm64/onnxruntime.xcframework.zip/onnxruntime.xcframework/ios-arm64_x86_64-simulator/onnxruntime.framework is a framework of static libraries, and will not be copied to the app.

I don't understand why, and I'm running out of ideas to fix this.

Thank you in advance for any help 🙌

(Note: this was first briefly mentioned here dotnet/sdk#36527)

Not sure if this should be directed towards Maui or the Runtime team, but probably Maui?

@Redth @jonathanpeppers should this go to the Maui team and which repo should we route it to? That MT error code I think is from the simulator, right?

Do we have a way to move this to https://github.com/xamarin/xamarin-macios?

You cant unless you use some sort of bot to duplicate the issue.

Maybe @dalexsoto @rolfbjarne have a github issue mover tool to move it?

[rolfbjarne]

Can you try adding this package, and see if that fixes it?

<PackageReference Include="Microsoft.ML.OnnxRuntime.Extensions.Dummy" Version="0.10.0-beta" />

Thank you for your help, it's really appreciated 🙌

I've tried this dependency (at 0.10.0-beta) as well as the latest version (0.12.0), and I still have the same symptoms / behavior.
