.NET Core is a free and open-source managed computer software framework for the Windows, Linux, and macOS operating systems.[3]

History[edit]

.NET Core 1.0 was released on June 27, 2016,[4] along with Microsoft Visual Studio 2015 Update 3, which enables .NET Core development.[5] .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 March 7, 2017.[6]

.NET Core 2.0 was released on August 14, 2017, along with Visual Studio 2017 15.3, ASP.NET Core 2.0, and Entity Framework Core 2.0.[7] .NET Core 2.1 was released on May 30, 2018.[8] .NET Core 2.2 was released on December 4, 2018.[9]

.NET Core 3 was announced on May 7, 2019, at Microsoft Build. Currently preview builds are available. An official release is planned for september 2019.[10] With .NET Core 3 the framework will get support for development of desktop application software, artificial intelligence/machine learning and IoT apps.[11]

Language support[edit]

.NET Core fully supports C# and F# and partially supports Visual Basic .NET.

Currently VB.NET compiles and runs on .NET Core, but the separate Visual Basic Runtime is not implemented. Microsoft announced that .NET Core 3 would include the Visual Basic Runtime.[19] As of October 2018, C++/CLI is not yet supported,[20] although support is planned on Windows.[21]

Architecture[edit]

.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.[22][23] .NET Core 3 supports desktop technologies WinForms, WPF and UWP.[24] .NET Core supports use of NuGet packages. Unlike .NET Framework, which is serviced using Windows Update, .NET Core relies on its package manager to receive updates.[22][23]

It consists of CoreCLR, a complete runtime implementation of the Common Language Runtime, which originated at Microsoft as the virtual machine for managing execution of .NET programs and includes a just-in-time compiler called RyuJIT.[25][a] .NET Core also contains CoreRT, the .NET Native runtime optimized to be integrated into AOT compiled native binaries.

.NET Core also includes CoreFX, which is a partial fork of .NET Framework standard libraries.[27] While .NET Core shares a subset of .NET Framework APIs, it comes with its own API that is not part of .NET Framework.[22] A variant of the .NET Core library is used for UWP.[28]

.NET Core's command-line interface offers an execution entry point for operating systems and provides developer services like compilation and package management.[29]

Notes[edit]
