System.Threading.Tasks.TaskCancelledException: about applicationinsights-owinextensions HOT 7 CLOSED

The accompanying call on the client application that observes this error is actually quite useful and may serve to suggest how to log the exception

A Task's exception(s) were not observed either by Waiting on the Task or accessing its Exception property. As a result, the unobserved exception was rethrown by the finalizer thread. Response status code does not indicate success: 500 (Internal Server Error)

This may be my only hope without changing the code:

Hi Colin,

Could you please say something more about your scenario. Do you control the client? Is the A Task's exception(s) were not observed... error something you see on the client when TaskCanceledException is logged in application insights? Do you also observe this problem when owin extensions are not used?

Hi Marcin, Yes we control the client too. I was reluctant to remove the middleware as our CI pipeline and getting us into our PerfTest environment is a little cumbersome (but I agree its a good test) . The "good thing" is that this really is a drop in the ocean and its a fraction of 1 percent of calls. I was just keen to get understanding of what the issue was. (I could fork and add additional logging, but I was reluctant to do this too as "in the main" the middleware works)

I am understanding that our architecture protects us from these failures anyway and will confirm this today, which makes this a known issue but a non issue "as it were".

Let me know if you are able to confirm that the middleware is causing the issues.
