An Introduction to C#.

C# is a programming language developed by Microsoft designed to develop both console and graphical applications.

C# was designed to be a simple, modern, general-purpose, object-oriented programming language. It supports multiple programming paradigms, including functional, imperative, and object-oriented

A C# program is composed of one or more source files that contain code written in the C# programming language. The program's source code is compiled into an executable file using a compiler that translates the code into machine instructions or assembly language that the computer's hardware can understand.

C# is a simple, modern, object-oriented programming language. It has many features that make it powerful and easy to use.

The C# language was designed to be like C++, but without the problems that can make C++ difficult.

The C# language is managed code. The compiler allocates memory and handles other tasks, so programmers don't have to worry about them. Managed code enables developers to write more robust programs because they don't need to spend their time managing memory or other low-level details.

Example of C# sample code.


using System;

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

History of the C# programming language?

C# is a general-purpose, object-oriented programming language. Originally developed by Microsoft, C# is now an open-source language. It has been adopted as the most popular programming language for writing .NET programs and libraries used to create Windows applications and Web services.

C# was introduced to Microsoft by Anders Hejlsberg and Mads Torgersen in November 1995 as part of the .NET framework.

C# is a general-purpose, multi-paradigm language that combines procedural, object-oriented, and functional programming elements. It includes a lightweight syntax and an implementation of the Common Language Runtime (CLR), on top of which .Net programs are built.

The CLR is a runtime environment for .NET applications that provides low-level services such as memory allocation, garbage collection, and common language runtime execution.

The CLR's primary responsibility is the interface between managed applications compiled for the .NET Framework and operating system services. The CLR manages the process of executing managed applications by performing all necessary load-time and runtime operations on behalf of the application. The CLR has two main components: a Just-in-Time (JIT) compiler and runtime.

The JIT compiles managed code into native machine code, then runs on the computer's processor. The runtime is responsible for managing and coordinating the execution of managed applications by providing functions that support garbage collection, memory management, thread scheduling, exception handling, cryptography and security services, I/O operations, and serialization.
