mediatR 12.41 breaking change with IRequest
After upgrading to mediatR 12.41. I now have breaking changes with my code.
I now get the error below when calling the
Send() in the screenshot.
'OrderCancelledCommand' cannot be used as type parameter 'TRequest' in the generic type or method 'ISender.Send<TRequest>(TRequest, CancellationToken)'.
However OrderCancelledCommand already implements IRequest<XXX>.
To fix this compiler error, I had to make iOrderCancelledCommand inherit IRequest as well. So
from
public class OrderCancelledCommand : IRequest<ReservationAmendmentResult> to
public class OrderCancelledCommand : IRequest<ReservationAmendmentResult>, IRequest
Any ideas if this is the proper way to fixing this and what's causing it?

thats weird, it works fine for me
you shouldnt implement both the generic and non generec IRequest
the non generic one is for void responses
try cleaning and rebuilding
