D.
Use the Tracing module to set logging variables with a Mapped Diagnostic Context
Answers
D.
Use the Tracing module to set logging variables with a Mapped Diagnostic Context
Suggested answer: D

Explanation:

To enrich every log message with the order ID, the developer should use the Tracing module to set logging variables with a Mapped Diagnostic Context (MDC). The Tracing module allows adding custom key-value pairs to log messages using MDC variables. The developer can use Set Logging Variables operation to set the order ID as an MDC variable and then use it in any logger processor within the same thread or event.
