Hi and thanks for informational video. I needed to ask - here 8:06 you mean using multiple OnStarting() on 1 middleware (if u meaned this then i understand you mean)? or you mean using OnStarting() method in different middlewares (i cant understand here - how can/will callbacks work in reversed order, if middlewares have his own work order)?

It is very interesting. Today I was working on a way to manipulate the actual response body. Minimal API does not have a way to do content negotiation and as such only responds with JSON data. What if I for example want to send XML data instead? I need a way (a filter perhaps) that checks the incoming header and when a Accept header is sent with "application/xml" it would modify the response and instead sends XML. So far I have not been able to be successful unfortunately but your content is helpful nonetheless as it helps me understand the whole process better.
