Configure output of 'Request already started' about middleware

[mschmidt98]

Hi again,
Could have thought about using the MS Log filter myself.

We are just switching to ASP.NET Core and I'm amazed every day by what this framework brings out of the box.

Anyway, that did the trick. Many thanks for the quick response :)

Is it possible, to configure/disable this "response already started" message, or do you have any other workaround?

There's no way to configure it outside ASP.NET Core's logging configuration, no.

If you're not interesting in seeing this, you probably want to just filter the message away, using ASP.NET Core's Log Filtering. If you configure Hellang.Middleware.ProblemDetails to have a minimum log level of Error, you should be able to get rid of that message, while still keeping the rest of the logging (all remaining logs are errors).

I should probably look into changing the logging level of that message to something less severe. I guess my thinking at the time was to have this middleware handle every single error state and warn the developer when that's not the case, but as it's becoming more and more common for MVC etc. to handle these, I think it makes sense to drop the level down a notch or two.
