Middleware can make or break your ASP.NET Core application…
And most developers underestimate where things go wrong.
In a recent exercise on custom middleware, one detail stood out more than the rest.
Here’s what really matters 👇
1️⃣ What middleware is actually doing
Middleware components sit in the request pipeline and enhance functionality like logging, authentication, and error handling.
Simple concept…
Powerful impact.
2️⃣ Why custom middleware is worth your time
Custom middleware lets you log request method, path, and response status code.
That visibility gives you real insight into how your app behaves in production.
3️⃣ The mistake most developers make 🛑
Logging before calling the next middleware.
That single placement error leads to incorrect status codes and misleading logs.
4️⃣ The fix that changes everything ✅
Move the logging logic after await next().
That way:
The request completes.
Redirects are resolved.
And the status code is accurate.
5️⃣ Middleware order is not optional
The pipeline runs top to bottom.
Where you place middleware determines:
What it sees…
What it captures…
And what it misses entirely.
The takeaway…
Custom middleware is incredibly powerful, but only when order and execution are intentional.
What’s one subtle ASP.NET Core mistake you’ve made that taught you more than any tutorial ever could?
Drop it in the comments… someone else will thank you for it.
