Handle and log OperationCanceledExceptions thrown due to client disconnects #150
Description
From @anpete on April 14, 2016 5:32
Not sure if this is expected, so filing just in case. While investigating our internal MusicStore stress scenario I'm seeing an OperationCanceledException raised occasionally when the number of clients > ~50.
Stack:
fail: Microsoft.AspNetCore.Diagnostics.ExceptionHandlerMiddleware[0]
An unhandled exception has occurred: The operation was canceled.
System.OperationCanceledException: The operation was canceled.
