Overview of .NET Framework and .NET Core

Both .NET Framework and .NET Core are software development frameworks created by Microsoft. They provide a set of tools, libraries, and components to help developers create a wide range of applications.

.NET Framework

It is introduced in 2002. The .NET Framework is a software development platform for building applications primarily for Windows. It includes a large class library, known as the Framework Class Library (FCL), and provides support for languages like C#, VB.NET, and F#.

Important Features

  1. Mainly used for Windows applications (like desktop software and websites).
  2. Includes built-in libraries to make coding easier.
  3. It works only on Windows.

.NET Core

It is introduced in 2016. .NET Core is a cross-platform version of the .NET framework. It was introduced to allow developers to create applications that can run on Windows, macOS, and Linux. It’s an open-source and more lightweight framework compared to the .NET Framework.

Important Features

  1. We can build apps for multiple operating systems.
  2. It’s faster and more modern than .NET Framework.
