What is ASP.NET Core and why was it created?

Mid .NET Core
Quick Answer ASP.NET Core is the cross-platform, open-source successor to ASP.NET Framework. It runs on Linux, macOS, and Windows — enabling container deployments. It's built with performance as a priority (one of the fastest web frameworks benchmarked), cloud-native design (12-factor app compatible), and a clean, modular pipeline replacing legacy HTTP handlers and modules.

Answer

ASP.NET Core is a modern, cross-platform, high-performance framework for building web applications. It was created to replace the heavy, Windows-only ASP.NET Framework. ASP.NET Core offers modularity, built-in DI, a redesigned hosting model, lightweight runtime, and full Linux + container support.
