For the current framework, see: ASP.NET

ASP.NET Core is an open-source web application framework, and the next generation of ASP.NET, developed by Microsoft and the community. It is a modular framework that runs on both the full .NET Framework, on Windows, and the cross-platform .NET Core.

The framework is a complete rewrite that unites technologies like ASP.NET MVC and Web API into a single programming model.


Originally, the framework was to be called ASP.NET 5[1] when ready. However, in order to avoid implying it is an update to the existing ASP.NET framework, Microsoft later changed the name to ASP.NET Core 1.0.[2]
