How to handle errors in side-channel streams?

[lostmsu]

I built a client-server pair that uses multiplexed streams, and when I interrupt the server the client simply sees the stream it got as ended with no exception thrown or any indication anything went wrong on the server side. How do I handle that?

It sounds like you want this feature: dotnet/Nerdbank.Streams#299, which first shipped in Nerdbank.Streams 2.10.37-alpha. Can you confirm which version of Nerdbank.Streams you're using?
