The path to dotnet is specified by settings: DotnetTestHostmanager: User specified custom path to dotnet host: 'C:\src\runtimelab\artifacts\bin\Swift.Bindings.Tests\Debug\net9.0\dotnet.exe'./

<RunSettings>
  <RunConfiguration>
   
    <DotNetHostPath>C:\src\runtimelab\artifacts\bin\Swift.Bindings.Tests\Debug\net9.0\dotnet.exe</DotNetHostPath>

  </RunConfiguration>

it is generated by target coming from here: https://github.com/dotnet/runtimelab/blob/feature/swift-bindings/eng/testing/runsettings.targets#L27

The latest commit in that repo (on the mentioned branch) does not build for me , but the previous commit 0ba0707 shows this as the content, which seems correct.

Thanks @nohwnd for finding out where it comes from - I tried... but obviously failed :-(
