Answer
Middleware components execute sequentially for every request. Each can inspect, modify, or short-circuit the pipeline. This modular pipeline replaces old HTTP modules/handlers and provides full control over request flow.
Quick Answer
Each middleware is a delegate that wraps the rest of the pipeline. When you call app.Use(async (context, next) => { ... await next(context); }), you're adding a step. Each middleware can short-circuit (return without calling next) or continue. The order is critical — authentication must come before authorization; routing before endpoint execution.
