2 years ago Maybe I'm wrong, but I want to check the cancellation token in my use case.
The class FluentMediator/src/FluentMediator/Pipelines/CancellablePipelineAsync/Pipeline.cs / is checking if the token is cancelled and throwing an exception. Probably here is my problem.
Hi guys,
I'm using FluentMediator in two of my projects. Last days I found an issue in my app where my requests get an OperationCancelledException. After a few hours trying to resolve, I found it on my Windows Event Viewers. It's looks like the FluentMediator crashing between my controller and my use case class. Can you guys check it out?
