Example given for factory-based middleware could have been clearer

[sateesh-pagolu]

The current example given in the documentation of factory-based middleware is not very clear. A real-time use case with more clear example would have been much helpful.
Same is the case with "Middleware activation with a third-party container".

Any link to other examples/documentation elsewhere will be much appreciated.

Hello and thanks for the feedback @5a7335h. The sample does show a real-world use case: the database context used in the sample is a scoped service. Can you elaborate on what you find confusing?

[guardrex]

Both topics don't focus on real-world middleware implementations ... they focus on middleware activation patterns. If you would like to see real-world middleware examples, your best bet is to search broadly for blog posts and GH repo examples.

Any link to other examples/documentation elsewhere will be much appreciated.

Yes, that's possible. We'd probably do that in the main middleware topic.

Thanks for your super fast response @guardrex. 👍
This discussion has clarified few things. Although the examples given in the documentation show the implementation of this concept, I was actually looking for a basic example that emphasizes the benefit of using IMiddleware and IMiddlewareFactory (Scoping for example?). I started looking for the blog posts to see more specific scenarios. I might find one soon. But thought I would share the feedback so that we would have more authentic example in MSDN docs.

Personally I find the class name IMiddlewareMiddleware jarring, since it looks like the name of an Interface not a class.

[guardrex]

I'd like to change the name to "FactoryActivatedMiddleware."
