An OutputType=Exe project build will create a runtimeconfig.dev.json which adds probing paths:

    "additionalProbingPaths": [
      "C:\\Users\\radu.oancea\\.dotnet\\store\\|arch|\\|tfm|",
      "C:\\Users\\radu.oancea\\.nuget\\packages"
    ]

Since all the dependencies should be near the AppHost, and the runtime probes in its directory first (e.g. I've used dotnet store first on my dependencies, but it still loaded them from the build folder), does runtimeconfig.dev.json have an effect?
