Why does middleware order matter in ASP.NET Core?

Mid .NET Core
Quick Answer Middleware is processed in the exact order it's added. Exception handling must come first to catch errors from all subsequent middleware. HTTPS redirection before authorization. Static files before routing (to short-circuit static requests). Authentication before authorization. Putting middleware in the wrong order causes bugs that only appear in production scenarios.

Answer

Middleware executes in the order registered. Incorrect ordering may break authentication, routing, exception handling, and endpoint execution. ASP.NET Core gives full control to developers and does not auto-correct middleware ordering.
