Pull request overview
This PR wires Coverlet’s XPlat Code Coverage data collector into the CI pipeline so test runs automatically generate Cobertura coverage output and upload it as a workflow artifact.
Changes:
- Add
--collect "XPlat Code Coverage" --settings tests/coverlet.runsettingsto the CIdotnet teststep so coverage is produced during test execution. - Upload
TestResults/**/coverage.cobertura.xmlas a dedicated CI artifact. - Introduce
tests/coverlet.runsettingsto scope and configure coverage collection/output.

coverlet.collectorandcoverlet.msbuildwere already present in the test project but never activated in CI. This wires them up so coverage data is collected and uploaded on every build.Changes
