Asp net core web server console output not visible in vs for net core 2 2

ASP.NET is a popular programming language used for developing web applications. It provides a powerful framework for dynamic and interactive . However, sometimes developers may encounter issues with the visibility of the console output in Visual Studio for ASP.NET Core 2.2 web server applications. In this article, we will explore this problem and provide solutions.

One common issue that developers face is the lack of visibility of the console output when running an ASP.NET Core 2.2 web server in Visual Studio. This can be frustrating as the console output is essential for debugging and monitoring the application's behavior.

To solve this problem, we can try the following steps:

1. Check the Output : In Visual Studio, go to the “View” menu and select “Output”. Make sure that the “Show output from” dropdown is set to “Debug”. This will display the console output in the Output Window.

2. Enable Console Logging: In your ASP.NET Core 2.2 web server application, open the `Program.cs` file. Look for the `CreateWebHostBuilder` method and add the following code inside it:


This code enables console logging for the web server application, ensuring that the console output is visible in Visual Studio.

3. Use Debug.WriteLine: Another approach is to use the `Debug.WriteLine` method to write messages to the console. This method writes the specified message to the Output Window in Visual Studio. For :

Debug.WriteLine(“This is a debug message”);

By `Debug.WriteLine`, you can log important information and debug your application without relying solely on the console output.

4. Use ILogger: ASP.NET Core provides a built-in logging framework called ILogger. You can use this framework to log messages and have more control over the logging process. To use ILogger, you need to inject it into your . For example:

private readonly ILogger _logger;

public HomeController(ILogger logger)
_logger = logger;

public IActionResult Index()
_logger.LogInformation(“This is a log message”);
return View();

By using ILogger, you can log messages at different levels (e.g., Information, Warning, Error) and configure the logging behavior according to your needs.

In conclusion, the lack of visibility of the console output in Visual Studio for ASP.NET Core 2.2 web server applications can be resolved by following the steps mentioned above. By checking the Output Window, console logging, using Debug.WriteLine, or utilizing the ILogger framework, developers can effectively debug and monitor their applications. to always test and verify the changes made to ensure the desired results.
