ASP.NET Core is the successor of the ASP.NET web-development platform. A robust, feature-rich framework for developing super-fast APIs for web apps, ASP.NET Core is open-source and cross-platform—a complete rewrite of ASP.NET that combines MVC structure and Web API into a single framework. In Sitefinity's 3-tier architecture, the
ASP.NET Core Renderer can be deployed and hosted on any platform that supports the ASP.NET Core framework.
