I'm in the process of creating a custom stream for an API endpoint in my app. The stream needs to have custom logic that I don't want to get into, but suffice to say I can't use a built-in stream class. I did the minimum necessary to implement a read-only stream (inheriting from System.IO.Stream) and I've verified that the System.IO.Bin...
