C# Diagnostics and Logging: From Development to Production

Every reliable application needs a way to report its health and diagnose issues, both during active development and after deployment. Understanding how to track down silent bugs and monitor runtime behavior is essential for any professional C# developer. This text-only course guides you through the foundational concepts of diagnostic logging in C#. You will start with the absolute basics of logging terminology, progress to configuring native diagnostic tools, and learn how to write clean, maintainable logs that do not degrade application performance. What you'll learn: - Understand the fundamental differences between development-time debugging and runtime tracing. - Implement native diagnostics using the C# Debug and Trace classes. - Configure custom trace listeners to route log output to files, consoles, or event logs. - Apply modern structured logging principles to make your log data easily searchable. - Write efficient log messages using string interpolation and appropriate log levels. - Manage logging configurations dynamically without rebuilding your application. The course begins with core definitions and diagnostic theory before guiding you through step-by-step written implementations, configuration setups, and modern logging best practices. It is designed for beginner to intermediate C# developers, requiring no prior experience with diagnostics or logging frameworks.
