CI: net6 build still fails with parallel build race on ScyllaDB.deps.json #204
Description
Description
The net6 CI job (integration-tests (PRIOR, net6, 6.0.x)) fails during make test-unit with a file locking error on ScyllaDB.deps.json:
error MSB4018: The "GenerateDepsFile" task failed unexpectedly.
System.IO.IOException: The process cannot access the file
'.../src/Cassandra/bin/Debug/netstandard2.0/ScyllaDB.deps.json'
because it is being used by another process.
PR #192 (fix/ci-parallel-build-race) was merged to address this, but the issue persists.
Reproduction
Observed in CI run: https://github.com/scylladb/csharp-driver/actions/runs/22953537794/job/66624477477
The failure is intermittent — it depends on timing of parallel MSBuild targets writing to the same output path.
