Hands-On Tutorials: Building Your First ASP.NET Web Application
Ready to dive into the world of ASP.NET? This hands-on guide will walk you through creating your first dynamic web application. We’ll cover everything from setting up your project to implementing real-time features. Let’s get started!
Step-by-Step Code Walkthrough
Start by launching Visual Studio and creating a new ASP.NET Core Web Application. Choose the “Web Application (Model-View-Controller)” template for a traditional MVC structure.
In the solution explorer, you’ll see folders for Models, Views, and Controllers. Right-click the Controllers folder and add a new Controller. Name it HomeController and replace the default code with:
using Microsoft.AspNetCore.Mvc;
namespace MyFirstApp.Controllers
{
public class HomeController : Controller
{
public IActionResult Index()
{
return View();
}
}
}This sets up a basic controller to handle requests to your homepage.

{
public class ChatHub : Hub
{
public async Task SendMessage(string user, string message)
{
await Clients.All.SendAsync("ReceiveMessage", user, message);
}
}
}Update your view to include a chat interface. Add this script to your Index.cshtml:
const connection = new signalR.HubConnectionBuilder().withUrl("/chatHub").build();
connection.on("ReceiveMessage", function (user, message) {
document.getElementById("chatLog").innerHTML += "<div>" + user + ": " + message + "</div>";
});
document.getElementById("sendButton").addEventListener("click", function () {
var user = document.getElementById("userInput").value;
var message = document.getElementById("messageInput").value;
connection.invoke("SendMessage", user, message).catch(function (err) {
