In this article I will provide a short Hello World Tutorial using a small Sample Program example on how to use and develop applications in ASP.Net Core 6 for the first time.
This article makes use of Visual Studio 2022 for developing the ASP.Net Core 6 Hello World Tutorial with Sample Program example.
Creating a new ASP.Net Core 6 Project
Let’s get started with creating your first ASP.Net Core 6 Project.
1. Open Visual Studio and click on Create a New Project.

3. You will need to provide a suitable Name to the View. This article does not use Layout Page and hence the “Use a layout page” CheckBox needs to be kept unchecked.

Enabling MVC and Configuring the Routes
The last important part is to enable MVC and configure the Routes in the Program.cs file.
1. Open the Program.cs class from the Solution Explorer window.

2. In the Program.cs, there are two configurations.
Configure MVC Services
Call the following function AddControllersWithViews which will instruct the program to add MVC Services.
Configure Routes
Then, the Route is set and the names of the Controller and the Action method are specified.
var builder = WebApplication.CreateBuilder(args);
//Enabling MVC
builder.Services.AddControllersWithViews();
var app = builder.Build();
//Configuring Routes
app.MapControllerRoute(
name: "default",
pattern: "{controller=Home}/{action=Index}/{id?}");
app.Run();
The final Program.cs file will look as shown below.

Displaying a Message from Controller to View in ASP.Net Core 6 Project
1. Inside the HomeController’s
Index Action method, a
ViewBag property named “Message” is set.
public class HomeController : Controller
{
public IActionResult Index()
{
ViewBag.Message = "This is my First MVC Core 6 App.";
return View();
}
}
2. The
ViewBag property is displayed in the
View named “Index” as shown below.
@{
Layout = null;
}
<!DOCTYPE html>
<html>
<head>
<meta name="viewport" content="width=device-width" />
<title>Index</title>
</head>
<body>
@ViewBag.Message
</body>
</html>
3. Now press F5 to run the application and you should see a message displayed on page in browser.
