all examples in RFA8.2.1 are using "SessionLayer.SessionLayerEventTypeEnum.OMMItemEvent" and OMMConsumer. But our server is code in C++ by RFA 7.6 with MarketDataItemEvent can be triggered.
(rfa::sessionLayer::MarketDataItemEvent ) Would you give me some examples of how to trigger MarketDataItemEvent in RFA8.2.1 ?
