What is Dot Net ?
Dot NET is a software framework developed by Microsoft that provides a platform for building, running, and deploying applications. The Dot NET framework includes a set of libraries and tools that enable developers to create a wide range of applications, from desktop and mobile applications to web services and cloud-based applications.
The Dot NET framework is based on the Common Language Runtime (CLR), which provides a number of key features, including automatic memory management, type safety, and exception handling. The CLR is responsible for compiling and executing Dot NET code, which can be written in a number of programming languages, including C#, Visual Basic, and F#.
Some of the key components of the Dot NET framework include:
- The Base Class Library (BCL), which provides a set of reusable classes and types that can be used by Dot NET applications.
- The Common Language Infrastructure (CLI), which defines a set of standards and specifications for Dot NET applications.
- ASP Dot NET, which is a web development framework that enables developers to create web applications using Dot NET.
- Windows Presentation Foundation (WPF), which is a framework for building desktop applications with rich user interfaces.
In addition to these components, the Dot NET framework also includes a number of tools and services for building and deploying applications, including Visual Studio (an integrated development environment), NuGet (a package manager), and Azure (a cloud computing platform).

Dot Net Code
Here’s an example of a simple “Hello, World!” program written in C# using the Dot NET framework:
class HelloWorld {
static void Main() {
Console.WriteLine("Hello, World!");
}
} In this program, we start by including the System namespace, which provides access to basic system functionality. We then define a class called HelloWorld , which contains a static method called Main() . This is the entry point of our program, and it’s where the execution starts.
Inside the Main()method, we use the Console .WriteLine()method to output the string “Hello, World!” to the console. The Console class is part of the System namespace and provides methods for interacting with the console.
To run this program, we would typically save the code in a file with the extension .cs, compile it using a C# compiler (such as the one included with Visual Studio), and then execute the resulting executable.
