Top level statements C# 9 and later

Context: Top-level statements (C# 9+) simplify code by removing ceremony. They are fully supported in .NET 10.

Top-level statements, introduced in C# 9, allow you to write code without the ceremony of a Main method, class, and namespace.

Benefits

• Simplicity: Focus on logic, not boilerplate
• Learnability: Easier for beginners
• Conciseness: Less code to write and read

Example Comparison

Traditional:

using System;

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

Top-level:

Console.WriteLine("Hello");
