.NET Framework Documentation

Welcome to the comprehensive documentation for the Microsoft .NET Framework. This section provides detailed information, guides, and API references for developing applications on the .NET platform.

What is .NET Framework?

The .NET Framework is a software development framework that is available for Microsoft Windows operating systems. It can be used to develop a wide range of applications, including Windows desktop applications, web applications, and services.

Key components include:

Common Language Runtime (CLR): The execution engine of the .NET Framework. It provides memory management, thread management, and exception handling.
.NET Base Class Library (BCL): A rich set of pre-written classes that provide fundamental functionalities for tasks such as string manipulation, file I/O, networking, and data access.
Language Interoperability: .NET supports multiple programming languages, allowing developers to choose the best language for their needs and enabling code written in different languages to interoperate seamlessly.
