I see that the errors are:

/Users/runner/.nuget/packages/microsoft.net.test.sdk/17.14.1/build/netcoreapp2.0/Microsoft.NET.Test.Sdk.targets(4,5):error : Microsoft.NET.Test.Sdk doesn't support net6.0 and has not been tested with it. Consider upgrading your TargetFramework to net8.0 or later. You may also set true in the project file to ignore this warning and attempt to run in this unsupported configuration at your own risk. [/Users/runner/work/pythonnet/pythonnet/src/embed_tests/Python.EmbeddingTest.csproj::TargetFramework=net6.0]

Is not something I Implemented... so i didn't commit my changes at the .csproj, but i think is enought to editPython.EmbeddingTest.csproj tag:

<PropertyGroup>    <TargetFrameworks>net472;net6.0</TargetFrameworks>  </PropertyGroup>

to latest .NET LTS:

<PropertyGroup>    <TargetFrameworks>net472;net8.0</TargetFrameworks>  </PropertyGroup>

Link to MS versioning:

Am I missing something?

Can i commit the project edit?

Sorry for the mess with the build. It's not quite as simple, I'm looking into updating our CI to use .NET 8 and uv, see#2612 and#2520. Once these are through, I'll revisit your PR.
