What is Console.Log Equivalent in C#?

In C# web-application or Console application you can use Debug.WriteLine() to print to output console or you can say "output" -> "Debug" tab.

I tried using it in C# .NET Core web-application using below C# Code

      public IActionResult Index()
        {
            var orders = _context.Orders.ToList();
            Debug.WriteLine("First Order Country is : " + orders.FirstOrDefault().Country);

            return View(orders);
        }

and here is the output:

You will need to add "using System.Diagnostics;" namespace.

Note: In Visual Studio Click on "View" and then in "Output" you will see the log when running your application.

OR

You can also use Trace.WriteLine() instead of Debug.Writeline()

Difference between Trace.WriteLine() and Debug.WriteLine() is that Debug.Writeline() statements will not be included in the Release compilation by default, whereas Trace.Writeline statements will be included.
