Logging in .NET Core Architectures

Logging is essential for observability and troubleshooting.

.NET Core provides a common ILogger<T> abstraction with pluggable providers (Console, Seq, Application Insights, Serilog).

Structured logging: Log properties, not just strings, for better querying and dashboards.

logger.LogInformation("Order {@Order} created", order);

Architecture impact: Consistent, structured logging across services enables effective monitoring and incident response.
