When I've heard "structured logging" used, it has been in the context of much more key-value pairs than just having keywords next to values, e.g.

    Log.Info("customerNum={customerNumber} transactionId={transactionId} state=completed", cN, tID)

or the ever popular logstash-y format:

    Log.Info(LogState.Add("state", "completed").Add("customerId", customerId).Add("transactionId", transactionId));

where `LogState` would build up a key-value dict and its `ToString` would emit the logstash JSON format.

I guess the version that works best depends on the tool that is consuming the log text.

In the end, serilog, depending on the sink, makes your log look like the template, and attaches the meta data of your template variable names and replacement values to the message itself.
