Overview of the .Net Framework Versions


Overview of the .Net Framework Versions - .NET Revolution

.NET Framework is a software development framework for building and running applications on Windows platform. .NET Framework is part of the .NET platform, a collection of technologies for building apps for Windows, Linux, macOS, Android, iOS, and many more.

The .Net Framework, a programming model that developed by Microsoft supports building as well as running applications for Windows, Windows servers, XML Web services, and Microsoft Azure. The framework includes a large class library called Framework Class Library (FCL) as well as Common Language Interoperability (CLR) across different programming languages like C++, C#, VB.Net, and F#. So there are many version have made with .Net Framework for various features. Let us start with the journey of .Net framework versions and their features.
