I just created my first .NET 6 console app, and instead of the default,
using System;
using System.Collections.Generic;
using System.Linq;
namespace MyApp
{
public class Program
{
public static void Main(string[] args)
{
Console.WriteLine("Hello World!");
}
}
}
I got:
// See https://aka.ms/new-console-template for more information
Console.WriteLine("Hello, World!");
And even when there's no class, the program runs, I took a look at the link provided in the comments. but I don't know if this is a new feature or an old one, If this is a new feature? does that mean C# will be allowing C-style programming hereafter?
It's a new feature of C# 9 or 10. Microsoft documentation says following:
Top-level statements enable you to avoid the extra ceremony required by placing your program's entry point in a static method in a class. The typical starting point for a new console application looks like the following code:
using System;
namespace Application
{
class Program
{
static void Main(string[] args)
{
Console.WriteLine("Hello World!");
}
}
}
The preceding code is the result of running the dotnet new console command and creating a new console application. Those 11 lines contain only one line of executable code. You can simplify that program with the new top-level statements feature. That enables you to remove all but two of the lines in this program:
Console.WriteLine("Hello, World!");
