Currently the installation via pip / uv fails. Same problems apply to Windows 10.

Building wheels for collected packages: pythonnet
DEPRECATION: Building 'pythonnet' using the legacy setup.py bdist_wheel mechanism, which will be removed in a future version. pip 25.3 will enforce this behaviour change. A possible replacement is to use the standardized build interface by setting the `--use-pep517` option, (possibly combined with `--no-build-isolation`), or adding a `pyproject.toml` file to the source tree of 'pythonnet'. Discussion can be found at https://github.com/pypa/pip/issues/6334
