.NET Core: Modern Framework for Building Scalable Applications

#webdev #programming #tutorial

Introduction to .NET Core

.NET Core is a modern, open-source, cross-platform framework for building scalable applications. Whether you're developing web applications, APIs, desktop apps, or microservices, .NET Core provides the tools and performance you need.

Key Features of .NET Core

High Performance

.NET Core is known for its exceptional performance. The framework includes:

  • Just-In-Time (JIT) compilation optimization
  • Native AOT (Ahead-of-Time) compilation for smaller deployments
  • Efficient memory management and garbage collection
  • Support for high-throughput, low-latency applications

Cross-Platform Compatibility

Build once and run on Windows, Linux, and macOS. This flexibility enables:

  • Containerized deployments with Docker
  • Cloud-native applications on Azure, AWS, and other platforms
  • Microservices architecture
  • Kubernetes orchestration

Modern Language Features

.NET Core supports cutting-edge C# features:

  • Record types for immutable data structures
  • Pattern matching for elegant code
  • Collection expressions for concise syntax
  • Nullable reference types for safer code
  • Async/await for responsive applications

Getting Started with .NET Core 

// Simple console application
using System;

class Program
{
    static void Main()
    {
        Console.WriteLine("Hello from .NET Core!");
        var result = 5 + 10;
        Console.WriteLine($"5 + 10 = {result}");
    }
}
Enter fullscreen mode Exit fullscreen mode

Building Web Applications

ASP.NET Core makes it easy to build robust web applications:

var builder = WebApplication.CreateBuilder(args);
var app = builder.Build();

app.MapGet("/", () => "Welcome to ASP.NET Core!");
app.Run();
Enter fullscreen mode Exit fullscreen mode
