🆚 ASP.NET Core vs. Flask

Microsoft ASP.NET Core is an open-source, cross-platform web framework and the successor to ASP.NET that enables development of web apps and APIs using .NET on Windows, macOS, or Linux.

It offers high performance via the Kestrel server, built-in dependency injection, unified MVC and Web API programming, minimal APIs, flexible configuration per environment, and side-by-side versioning.

Flask is a lightweight framework for building web applications in Python.

It provides a minimal core that includes URL routing, request/response handling, a built-in development server and debugger, Jinja2 as templating engine, support for RESTful APIs, and the ability to extend functionality via numerous third-party libraries.
