About

Microsoft.Extensions.Logging.Abstractions provides abstractions of logging. Interfaces defined in this package are implemented by classes in Microsoft.Extensions.Logging and other logging packages.

This package includes a logging source generator that produces highly efficient and optimized code for logging message methods.

Key Features

Define main logging abstraction interfaces like ILogger, ILoggerFactory, ILoggerProvider, etc.

How to Use

Custom logger provider implementation example

using Microsoft.Extensions.Logging;

public sealed class ColorConsoleLogger : ILogger
{
    private readonly string _name;
    private readonly Func<ColorConsoleLoggerConfiguration> _getCurrentConfig;

    public ColorConsoleLogger(
        string name,
        Func<ColorConsoleLoggerConfiguration> getCurrentConfig) =>
        (_name, _getCurrentConfig) = (name, getCurrentConfig);

    public IDisposable? BeginScope<TState>(TState state) where TState : notnull => default!;

    public bool IsEnabled(LogLevel logLevel) =>
        _getCurrentConfig().LogLevelToColorMap.ContainsKey(logLevel);

    public void Log<TState>(
        LogLevel logLevel,
        EventId eventId,
        TState state,
        Exception? exception,
        Func<TState, Exception?, string> formatter)
    {
        if (!IsEnabled(logLevel))
        {
            return;
        }

        ColorConsoleLoggerConfiguration config = _getCurrentConfig();
        if (config.EventId == 0 || config.EventId == eventId.Id)
        {
            ConsoleColor originalColor = Console.ForegroundColor;

            Console.ForegroundColor = config.LogLevelToColorMap[logLevel];
            Console.WriteLine($"[{eventId.Id,2}: {logLevel,-12}]");

            Console.ForegroundColor = originalColor;
            Console.Write($"     {_name} - ");

            Console.ForegroundColor = config.LogLevelToColorMap[logLevel];
            Console.Write($"{formatter(state, exception)}");

            Console.ForegroundColor = originalColor;
            Console.WriteLine();
        }
    }
}

Create logs


// Worker class that uses logger implementation of teh interface ILogger<T>

public sealed class Worker : BackgroundService
{
    private readonly ILogger<Worker> _logger;

    public Worker(ILogger<Worker> logger) =>
        _logger = logger;

    protected override async Task ExecuteAsync(CancellationToken stoppingToken)
    {
        while (!stoppingToken.IsCancellationRequested)
        {
            _logger.LogInformation("Worker running at: {time}", DateTimeOffset.UtcNow);
            await Task.Delay(1_000, stoppingToken);
        }
    }
}

Use source generator

public static partial class Log
{
    [LoggerMessage(
        EventId = 0,
        Level = LogLevel.Critical,
        Message = "Could not open socket to `{hostName}`")]
    public static partial void CouldNotOpenSocket(this ILogger logger, string hostName);
}

public partial class InstanceLoggingExample
{
    private readonly ILogger _logger;

    public InstanceLoggingExample(ILogger logger)
    {
        _logger = logger;
    }

    [LoggerMessage(
        EventId = 0,
        Level = LogLevel.Critical,
        Message = "Could not open socket to `{hostName}`")]
    public partial void CouldNotOpenSocket(string hostName);
}
