Asp.Net Core Logging

Logging is a crucial part of any application, especially for large applications logging is very important in production environment where debugging is not straight forward. The Asp.Net Core framework provides built-in support for logging.

In Asp.Net Core logging support is provided by the Microsoft.Extensions.Logging namespace. This namespace provides the following classes and interfaces to support Logging.

ILoggingFactory – Used to create ILogger type and to add ILogProvider instance. ASP.NET Core runtime creates an instance of LoggerFactory class and registers it for ILoggerFactory when the application starts, hence we can use ILoggerFactory interface anywhere in your application. The IoC container will pass an instance of LoggerFactory.

ILoggingProvider – Used to create and manage loggers

ILogger – Includes methods to implement the actual logging to various log destinations.

LoggingFactory – The class which implements ILoggingFactory. ASP.NET Core framework includes built-in LoggerFactory class that implements ILoggerFactory interface.

ASP.NET Core provides the following Logging Providers:

Console

Debug
