.NET Core is a free and open-source managed computer software framework for the Microsoft Windows, Apple macOS and Linux operating systems. It consists of CoreCLR, a complete runtime implementation of CLR, the virtual machine that manages the execution of .NET programs. CoreCLR comes with an improved just-in-time compiler, called RyuJIT.[a] .NET Core also includes CoreFX, which is a partial fork of FCL. While .NET Core shares a subset of .NET Framework APIs, it comes with its own API that is not part of .NET Framework. Further, .NET Core contains CoreRT, the .NET Native runtime optimized to be integrated into AOT compiled native binaries. A variant of the .NET Core library is used for UWP. .NET Core's command-line interface offers an execution entry point for operating systems and provides developer services like compilation and package management.

.NET Core supports four cross-platform scenarios: ASP.NET Core web apps, command-line apps, libraries, and Universal Windows Platform apps. It does not currently implement Windows Forms or WPF which render the standard GUI for desktop software on Windows. Microsoft announced in 2018 that .NET Core 3 will support desktop technologies WinForms, WPF and UWP. .NET Core is also modular, meaning that instead of assemblies, developers work with NuGet packages. Unlike .NET Framework, which is serviced using Windows Update, .NET Core relies on its package manager to receive updates.
.NET Core 1.0 was released on 27 June 2016, along with Microsoft Visual Studio 2015 Update 3, which enables .NET Core development. NET Core 1.0.4 and .NET Core 1.1.1 were released along with .NET Core Tools 1.0 and Visual Studio 2017 on 7 March 2017.
.NET Core 3 was announced on May 7, 2018 at Microsoft Build. A public preview release is planned for the end of 2018 and an official release is planned for 2019. With .NET Core 3 the framework will get support for development of desktop application software, artificial intelligence/machine learning and IoT apps.
