ASP.NET - ASP.NET Core is a modern

ASP.NET Core is a modern, redesigned version of ASP.NET. It is cross-platform, meaning applications can run on Windows, Linux, and macOS. It is optimized for performance and cloud deployment.

Core uses a unified framework for web apps and APIs. It removes legacy dependencies and provides a minimal, modular architecture. Developers include only required components, reducing memory usage.

ASP.NET Core uses a built-in web server called Kestrel, which is fast and lightweight. It can run standalone or behind reverse proxies like IIS or Nginx.

Configuration in Core is flexible and supports JSON files, environment variables, and command-line arguments. This makes it ideal for DevOps and microservices.

ASP.NET Core is the current and future standard. Learning older ASP.NET without Core has limited practical value.
