.NET Core, the reinvention of the Microsoft .NET Framework as an open source, cross-platform development choice, is a key focus of the upcoming features planned for the Visual Studio IDE.

In conjunction with .NET Standard -- a spec detailing what .NET APIs should be available on all .NET implementations -- .NET Core retains compatibility with .NET Framework, Xamarin and Mono while letting developers use Windows, macOS or Linux machines to code for mobile, cloud and embedded/IoT projects.

While still primarily driven by Microsoft dev teams, .NET Core is hosted on a GitHub repository and is supported by the .NET Foundation, an independent organization created by Microsoft three years ago to improve its open source development and collaboration.

Peeking at the Visual Studio Roadmap (updated last week) reveals .NET Core figures prominently in upcoming functionality for the IDE, both in the near-term and long:
