How to Use NLog in .NET Core

Benefits of Using NLog for Logging in .NET Projects NLog is a powerful, flexible, and high-performance logging framework widely used in .NET applications (including .NET Framework, .NET Core, and .NET 5/6/7/8+). Integrating NLog into .NET projects can significantly enhance system observability, maintainability, and debugging efficiency. Here are the main advantages of using NLog. I. Core Advantages 1. High Performance with Low Overhead NLog is highly optimized, utilizing asynchronous writing, buffering, and batch processing mechanisms that have minimal impact on application performance. Supports asynchronous logging (async="true") to prevent I/O from blocking the main thread. 2. Flexible Configuration Options Supports externalized configuration through XML configuration files (like nlog.config), allowing adjustments to logging behavior without recompiling code. Also supports code-based configuration for dynamic scenarios or cloud-native environments. 3. Rich Output Targets NLog supports writing logs to multiple targets simultaneously, including: ...
