Start with the fortunes, fortunes_dapper, and fortunes_ef benchmark results and the Benchmarks.dll dependency comparison, then review the linked PowerBI Dashboard. The issue does not name files or tests, and it does not define an expected code change or completion condition, so scope must be established before implementation.
