.NET Framework (pronounced dot net) is a product of Microsoft. It is a programming framework used by Software applications in order to run.[1] It has two major parts: the Common Language Runtime (CLR) and the .NET Framework Class Library. The CLR is an execution engine used to handle running programs. The class library provides a library of reusable code that applications can use.[2] These are designed to greatly simplify the development of larger applications.[2] .NET Framework supports Object-oriented programming (OOP).[3] Everything in .NET is contained in an object.[3] It also greatly simplifies Windows programming.[3]
Often, a program will ask for a particular version of .NET Framework to be installed (see below).[4] It is usually recommended to install the latest version your operating system (OS) will support.[4] This is because of backward compatibility; the newer version will also support older versions.
Visual Studio is the major development tool for .NET Framework. Visual Studio 2013 Community Edition is the first full-featured edition for personal development. It also has compilers for computer programming languages such as C++ and others.
