# This workflow builds and tests the Python implementation of TsFile on
# Windows using the MSVC toolchain, as a complement to unit-test-python.yml
# which builds the Windows target with MinGW.
#
# The C++ shared library (libtsfile) is built with the v141 toolset (the
# Visual Studio 2017 compiler) to match the VS 2017 support this branch
# targets. The Cython extension links to it through the plain C wrapper ABI,
# so it builds cleanly with whichever MSVC toolset setuptools selects.
