The platform .NET is liked for the making of enterprise applications as it has excellent integration with other Microsoft technologies, powerful features, and development tools that are easy to use. .NET Development has faced several changes over the years. There have been some notable changes in this sphere such as:

Introduction of .NET Core:
An open-source framework, .NET Core is a cross-platform for developing secure, scalable, and high-performance applications on Windows, Linux, and macOS. It has advanced scalability, security, and improved performance unlike the former – .NET Framework. Here is an example of creating a simple console application using .NET Core:

using System;

namespace HelloWorld
{
    class Program
    {
        static void Main(string[] args)
        {
            Console.WriteLine("Hello World!");
        }
    }
}


Introduction of C# 8.0:
C# 8.0 was released with new features and improvements which included nullable reference types, switch expressions, and async streams, for instance:

string result = statusCode switch
{
    200 => "OK",
    400 => "Bad Request",
    401 => "Unauthorized",
    404 => "Not Found",
    _ => "Unknown"
};


ASP.NET Enhancements:
ASP.NET is a common web development framework permitting developers to construct web applications in C#. Some of the enhancements include amplified backing for cloud-based apps, increased efficiency, and better linking with other Azure Microsoft products. Below is creating a simple ASP.NET web application:

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

namespace HelloWorldWeb
{
    public class Startup
    {
        public void ConfigureServices(IServiceCollection services)
        {
            services.AddControllers();
        }

        public void Configure(IApplicationBuilder app, IWebHostEnvironment env)
        {
            app.UseRouting();

            app.UseEndpoints(endpoints =>
            {
                endpoints.MapControllers();
            });
        }
    }

    public class HelloWorldController : Controller
    {
        [HttpGet]
        [Route("api/helloworld")]
        public IActionResult Get()
        {
            return Ok("Hello World");
        }
    }
}


Entity Framework Core:
A new test is Entity Framework Core. It’s a system that aids designers in working with databases using C# language, mainly designed for object-relational mapping (ORM). For instance, the newer EF Core is faster than the .NET Framework and supports multi-platform development better as well as has much better integration with other Microsoft products.

Visual Studio:
Visual studio is an Integrated Development Environment (IDE) used to create, debug, and deploy .NET applications. Code editors such as code writers assist developers in writing, debugging, and deploying code while you are testing your project.

In general terms, these changes have made development on .Net much more convenient allowing developers to create highly performing applications that are scalable and secure for various platforms including those involving mobile computing.
