[PowerBI Dashboard](https://aka.ms/aspnet/benchmarks)

@sebastienros

Start with the fortunes, fortunes_ef, and single_query benchmark results and the linked PowerBI dashboard, then compare the listed Microsoft.AspNetCore and Microsoft.NETCore dependency change. Reproduce the regression across the reported versions and identify the responsible change; done means the affected scenarios recover their prior performance without regressions.
