FluentLoggerExtensions

Fluent extensions for Microsoft.Extensions.Logging that capture caller file, member, and line information and prepend it to your log messages.

Install

• From NuGet: dotnet add package FluentLoggerExtensions
• Or reference the project directly in your solution.

Usage

using FluentLogger;
using Microsoft.Extensions.Logging;

var logger = loggerFactory.CreateLogger<Program>();

logger.WithCaller().LogInformation("Processing {RequestId}", requestId);
// Logs something like: [Program.cs:Main:42] Processing 12345

logger.WithCaller().LogError("Failed to process {RequestId}: {Reason}", requestId, reason);

API

• ILogger.WithCaller([CallerFilePath] file, [CallerMemberName] member, [CallerLineNumber] line) returns a CallerLogContext with captured caller info.
• CallerLogContext.LogInformation|LogWarning|LogError|LogDebug log with a [{File}:{Member}:{Line}] prefix while preserving structured logging args.

Requirements
