ASP.NET Core is an open-source and cross-platform framework for building modern cloud-based internet-connected applications, such as web apps, IoT apps, and mobile backends. ASP.NET Core apps run on .NET, a free, cross-platform, and open-source application runtime. It was architected to provide an optimized development framework for apps that are deployed to the cloud or run on-premises. It consists of modular components with minimal overhead, so you retain flexibility while constructing your solutions. You can develop and run your ASP.NET Core apps cross-platform on Windows, Mac, and Linux. Learn more about ASP.NET Core.
Follow the Getting Started instructions.
Also check out the .NET Homepage for released versions of .NET, getting started guides, and learning resources.

Code of conduct
This table includes links to download the latest builds of the ASP.NET Core Shared Framework. Also included are links to download the Windows Hosting Bundle, which includes the ASP.NET Core Shared Framework, the .NET Runtime Shared Framework, and the IIS plugin (ASP.NET Core Module).
