solution not found: {solution}

Error message

solution not found: {solution}

What it means

read_solution_connector_projects validates that the solution file (default StockSharp.slnx) exists before parsing it. If the file path does not resolve to an actual file, it raises ValueError. The .slnx format is an XML-based solution format used by newer .NET tooling.

Solutions

1. Verify the solution file exists: run from the repository root where StockSharp.slnx lives.
2. Use --solution to pass the correct absolute or relative path.
3. If the file was renamed, update the script's default or pass the new name via --solution.

Example fix

# before
python scripts/check-solution-connectors.py --solution wrong-name.slnx
# ERROR: solution not found: wrong-name.slnx

# after
python scripts/check-solution-connectors.py --solution StockSharp.slnx

solution_path = Path("StockSharp.slnx").resolve()
if not solution_path.is_file():
    print(f"Solution file not found: {solution_path}")
    sys.exit(1)

When it happens

Trigger: Running check-solution-connectors.py with a --solution path that does not exist, or when the default StockSharp.slnx has been renamed, moved, or deleted.

Common situations: Running from a subdirectory where the relative path doesn't resolve; using --solution with a typo; the .slnx file was renamed in a solution-format refactor but the script default was not updated.
