The child workflow is composed from some existing activities. This child workflow is treated as an activity in the master workflow. Sometimes we may need to track the internal activity execution information of the child workflow. However even if ActivityStateQuery.ActivityName is set to "*", the tracking information is only from the master workflow.
To get the tracking information of the child workflow, we can do one of the following:
1. Set TrackingProfile to null in the tracking participant.
2. Set the specific internal activity name of the child workflow to ActivityStateQuery.ActivityName
