.NET is a popular framework developed by Microsoft that supports building and running software applications for Windows, macOS, and Linux. It provides a comprehensive programming model and is used to create a variety of applications, including web applications, desktop applications, mobile apps, cloud-based services, and IoT (Internet of Things) devices. .NET offers a rich set of libraries, language interoperability, and support for multiple programming languages. One key component of .NET is the Common Language Runtime (CLR), which manages the execution of .NET programs and provides services such as memory management, exception handling, and security. Another essential aspect is the .NET Class Library, which offers a wide range of pre-built classes and functions that can be used by developers to expedite the development process. Let's consider an example using C# language, which is a popular language for .NET development. Below is a simple console application that displays "Hello, World!". using System; class Program { static void Main() { Console.WriteLine("Hello, World!"); } } In this example, we utilize the .NET Framework's Console class to output the "Hello, World!" message to the console. Furthermore, .NET encompasses various technologies, such as ASP.NET for web development, Xamarin for cross-platform mobile development, and Entity Framework for data access. These diverse components collectively provide a robust and versatile platform for software development.
