3- Then inside the AppEventReceiver.svc i entered code this code + the methods implementation:-
public SPRemoteEventResult ProcessEvent(SPRemoteEventProperties properties)
{
SPRemoteEventResult result = new SPRemoteEventResult();
switch (properties.EventType)
{
case SPRemoteEventType.AppInstalled:
HandleAppInstalled(properties);
break;
case SPRemoteEventType.AppUninstalling:
HandleAppUninstalling(properties);
break;
case SPRemoteEventType.ItemAdded:
HandleItemAdded(properties);
break;
}
return result;
}
