test-csharp.yml

name: Test — C#

# Exercises the whole regression pipeline for C#:
#   1. Build srcml from source on ubuntu-24.04-arm via the ci-ubuntu cmake workflow preset.
#   2. Collect the .deb produced by CPack.
#   3. Run the reusable regression-test.yml against the current C# baselines.
#
# Requires: a baseline release must already be published for each project
# (run baseline-csharp.yml first).
