Serilog is a diagnostic logging library for .NET applications with first-class support for structured event data. It captures named properties from message templates so logs can be searched and analyzed without parsing, and writes to files, console, and many other sinks.

Use cases

• add structured logging to a .NET application
• log events as JSON for log aggregation platforms
• instrument ASP.NET Core apps with rich diagnostics
• search application logs by property values instead of regex
• write logs to console, files, and external sinks
• capture object state in log events for debugging distributed systems

When to choose

• you're building .NET applications and want structured, queryable logs
• you need flexible output targets (console, file, Seq, Elasticsearch, etc.) via sinks
• you want a clean, easy-to-configure logging API with active maintenance

When to avoid

• you're not on a .NET platform
• you only need trivial plain-text logging and want zero dependencies
• your team is standardized on another logging facade like Microsoft.Extensions.Logging alone
