Agreed. This is so true. I've never ended up with a "library" for doing this. At my previous employer we had three different CQRS-based systems and two of the three of them even had completely different implementations for 90% of the CQRS infrastructure. They are both successful implementations and there was no need to share that bit of the code, as the two teams doing things came to different conclusions on how they wanted to write their CQRS code. The only thing we shared was the event store and some of the minor things on top of the event store.
