What is LOGGING in .NET [8.0] MVC?

Logging in .NET MVC is a mechanism to track and record events that occur while an application is running. It's a crucial aspect of software development for several reasons:

Debugging: Logs provide detailed context about what the application was doing at a specific point in time. This information can be invaluable when trying to understand and fix bugs.
Monitoring: By regularly reviewing logs, you can monitor the health of your application, identify patterns, detect anomalies, and spot potential issues before they become problems.
Auditing: Logs can serve as an audit trail, providing a record of actions taken by users or the system itself. This can be important for security and compliance purposes.

In .NET MVC, you can use the built-in ILogger interface for logging. This interface provides methods for logging at different levels of severity (Trace, Debug, Information, Warning, Error, Critical).

Here's an example of how you might use it in a controller:

public class HomeController : Controller
{
    private readonly ILogger _logger;

    public HomeController(ILogger<HomeController> logger)
    {
        _logger = logger;
    }

    public IActionResult Index()
    {
        _logger.LogInformation("Home/Index was called");

        return View();
    }
}

In the example above,

An ILogger is injected into the HomeController through its constructor (this is done automatically by ASP.NET Core's dependency injection system). Then, in the Index action method, a log message is written at the Information level.

N-Tier Architecture in asp.net core projects.

Breaking up .NET projects into smaller pieces (N-TIER Architecture)

Today i am going to be showing you how to implement N-Tier Architecture in your asp.net core projects This is a project that i am doing to learn EntityFrameWorkCore. You can have a look at my Github

This is the default project directory (MVC Project)
I have created different Class Library projects in the main Solution

The WikiCoding.DataAccess folder will be used for DataContext and Data Related stuffs. Eg, migration, table creation etc.

I have moved the Models folder to the WikiCoding_Models folder. As you can see. I am breaking the projects into smaller pieces. This is the core principle of N-Tier Architecture.
