I want write "Hello World" with ASP.NET Core.

Question

I want write "Hello World" with ASP.NET Core. Can you help me?

Answer 1

1. Create a New ASP.NET Core Web Application: Open Visual Studio and create a new project. Select "ASP.NET Core Web Application" from the available project types.
2. Choose ASP.NET Core Template: In the project creation wizard, select the ASP.NET Core template. You can choose either ASP.NET Core MVC or ASP.NET Core Razor Pages, depending on your preference.
3. Configure the Project: Configure the project settings such as the project name, solution name, and location. Click "Create" to generate the project files.
4. Write the "Hello World" Code: Open the HomeController.cs file (for MVC) or Index.cshtml.cs file (for Razor Pages) in the Controllers or Pages folder, respectively. Write the following code to display "Hello World":

For MVC

using Microsoft.AspNetCore.Mvc;

namespace YourNamespace.Controllers
{
    public class HomeController : Controller
    {
        public IActionResult Index()
        {
            return Content("Hello World");
        }
    }
}

For Razor Pages:

using Microsoft.AspNetCore.Mvc.RazorPages;

namespace YourNamespace.Pages
{
    public class IndexModel : PageModel
    {
        public void OnGet()
        {
            ViewData["Message"] = "Hello World";
        }
    }
}

1. Run the Application: Press F5 or click on the "Play" button in Visual Studio to build and run the application. Open a web browser and navigate to the URL displayed in the output window. You should see "Hello World" displayed on the webpage.
