.NET Web Development

Dive into the world of building modern, scalable, and high-performance web applications with the .NET ecosystem. This documentation covers everything from foundational concepts to advanced frameworks and best practices.

Key Technologies and Frameworks

The .NET platform offers a robust set of tools and frameworks for web development. Explore the following:

🚀

ASP.NET Core

The latest generation of ASP.NET, designed for cross-platform development, high performance, and cloud-native applications. Learn about MVC, Razor Pages, Blazor, and Web APIs.

🌐

Blazor

A revolutionary framework that allows developers to build interactive client-side web UIs with .NET. Run C# code directly in the browser with WebAssembly or on the server.

📦

SignalR

Enable real-time web functionality, such as live updates and chat applications, using SignalR for .NET.

Getting Started

Begin your journey with .NET web development. Here are some essential starting points:

Start Building with ASP.NET Core Start Building with Blazor

Core Concepts

  • Architecture: Understand patterns like MVC, MVVM, and Razor Pages.
  • Data Access: Learn Entity Framework Core for robust data persistence.
  • Security: Implement authentication, authorization, and protect your applications.
  • Deployment: Strategies for deploying .NET web apps to various platforms.
  • Performance: Tips and techniques for optimizing your web applications.

Code Examples and Tutorials

Explore practical examples and step-by-step tutorials to reinforce your understanding:

Example: Creating a Simple API with ASP.NET Core


using Microsoft.AspNetCore.Builder;
using Microsoft.AspNetCore.Hosting;
using Microsoft.AspNetCore.Http;
using Microsoft.Extensions.DependencyInjection;
using Microsoft.Extensions.Hosting;

var builder = WebApplication.CreateBuilder(args);
builder.Services.AddControllers(); // Add controllers for API endpoints

var app = builder.Build();

if (app.Environment.IsDevelopment())
{
    app.UseDeveloperExceptionPage();
}

app.MapGet("/", () => "Hello World from .NET!");

app.MapControllers(); // Map attribute-routed API controllers

app.Run();
                    

This basic example demonstrates setting up a minimal ASP.NET Core application that can serve simple HTTP requests and host API controllers.

Example: A Basic Blazor Component


<!-- Counter.razor -->
<h1>Counter</h1>

<p>Current count: @currentCount</p>

<button class="btn btn-primary" @onclick="IncrementCount">Click me</button>

@code {
    private int currentCount = 0;

    private void IncrementCount()
    {
        currentCount++;
    }
}
                    

This Razor component defines a simple counter that increments its value when the button is clicked. It showcases Blazor's component model and event handling.
