问题描述

获取此异常

无法传递实例ID为"b28da54b-e0ec-4d49-9b5c-caacebf46b88"的接口类型"ContentApprovalNavgation.INavigationService"上的事件"Next".

getting this exception

Event "Next" on interface type "ContentApprovalNavgation.INavigationService" for instance id "b28da54b-e0ec-4d49-9b5c-caacebf46b88" cannot be delivered.

推荐答案

为此是我遇到的可能原因

没有将事件声明为可序列化，
没有在handleexternalevent的位置定义正确的事件.

For this these are the possible reasons which i have encountered

Not declaring the events as serializable,
Not defining the correct event in the handleexternalevent''s place.
