説明
I have a WebApi endpoint that parses out the Request.Body itself rather than using Model binding due to performance reasons.
During some requests, I was getting a TaskCanceledException from a TextReader that I never gave any CancellationTokens too. After investigation, I found out that any read operations on the Request.Body after the Request was aborted will throw TaskCanceledExceptions. The stack trace at the time didn't list any Kestrel level code so I spent a lot of time trying to find out how a Stream can possibly cancel a token I never gave it.
This is a bit misleading and should probably change I think.
