+#### Notes for .NET Developers
+
+Don't try to tell "you're running from `dotnet run` and don't `dotnet run -c Release`", see the output first: `Hosting environment: Production`. It doesn't matter if you run `dotnet run` without arguments: if the configuration file says production or you don't use `if debug then do that`, then it runs as production.
