.NET is a free, open-source framework created by Microsoft for building various types of applications, including desktop, Web, mobile, gaming, IoT, and more. It provides developers with a platform to write applications in various programming languages, such as C#, F#, and Visual Basic, and runs on multiple platforms, including Windows, Linux, and macOS.

.NET works by compiling code written in one of the supported programming languages into a common intermediate language (CIL), which is then executed by the .NET runtime environment. This approach allows developers to write code in a language of their choice and still have it run on any platform that supports the .NET runtime.

Some of the key features of .NET include:

• Object-oriented programming: .NET provides developers with a powerful object-oriented programming model, making it easy to build complex applications.
• Common Language Runtime (CLR): The CLR is the heart of .NET and provides services such as memory management, security, and exception handling.
• Class Library: .NET includes a comprehensive class library that allows developers to use a set of pre-built code components to build applications quickly and easily.
• Language interoperability: .NET allows code written in different programming languages to be used together seamlessly.
• Cross-platform support: .NET runs on multiple platforms, including Windows, Linux, and macOS, making it a versatile framework for developers.
