MediatR.Examples.Lamar doesn't seem to be invoking any of the Exception Handlers

I am running MediatR.Examples.Lamar.Program (master) to learn MediatR to spike a solution for our project. The results show none of the exception handlers are being invoked. I updated Lamar to 4.3.0, same result. It also appears to the same for AspNetCore and StructureMap. It is not clear to me if it is bug with the Example or MediatR itself. Tried but couldn’t figure out where the bug is. Here’s the output from running Lamar example (I was expecting to see Y for exception handling tests):

Request Handler....................................................Y
Void Request Handler...............................................Y
Pipeline Behavior..................................................Y
Pre-Processor......................................................Y
Post-Processor.....................................................Y
Constrained Post-Processor.........................................Y
Ordered Behaviors..................................................Y
Notification Handler...............................................Y
Notification Handlers..............................................Y
Constrained Notification Handler...................................Y
Covariant Notification Handler.....................................Y
Handler for inherited request with same exception used.............N
Handler for inherited request with base exception used.............N
Handler for request with less specific exception used by priority..N
Preferred handler for inherited request with base exception used...N
Overridden handler for inherited request with same exception used..N

Sorry for late reply. Yes, it works.

I don’t have a mac to test on, can you pull the latest commit on the branch I made and see if it works?
