A "Hello, World!"program is usually a simple computer program that emits displays to the screen (often the console) a message similar to "Hello, World!".A small piece of code in most general-purpose programming languages, this program is used to illustrate a language's basic syntax.
The following is a very simple C# program, a version of the classic "Hello world" example using the top-level statements feature introduced in C# 9: [111] System . Console .

The XAML file declaratively defines the layout, contents and other properties of the UI element, while the C# file allows exposure of code entry points for interactivity. [4] A basic example of an interactive Hello, World! program could be created like so: MainWindow.xaml:
"Hello, World!" program by Brian Kernighan (1978) The "hello, world" example that appeared in the first edition of K&R has become the model for an introductory program in most programming textbooks. The program prints "hello, world" to the standard output, which is usually a terminal or screen display. The original version was: [36]
This is a feature of C# 9.0. Similar to in scripting languages, top-level statements removes the ceremony of having to declare the Program class with a Main method. Instead, statements can be written directly in one specific file, and that file will be the entry point of the program. Code in other files will still have to be defined in classes.

In most of today's popular programming languages and operating systems, a computer program usually only has a single entry point.. In C, C++, D, Zig, Rust and Kotlin programs this is a function named main; in Java it is a static method named main (although the class must be specified at the invocation time), and in C# it is a static method named Main.
