The .NET platform continues to move forward and evolve, and now it’s usefulness is extending into more target-platforms. As of 2017 August 14th, .NET Core 2.0 is available as a final release. Now, you can develop against this as your primary target version of .NET and expect to run your software on Windows, MacOS, and Linux (see here for a list of supported OS versions).
You can download the bits and view installation instructions here . Note that Docker images are available too.
You will want to update your version of Microsoft Visual Studio to Version 15.3 also. This update brings you a significant set of fixes and incremental improvements.
If you are developing websites using ASP.NET-MVC, you can access the GitHub repo for the new Core version here.
