Surface SDK TagVisualizationHostAdapter 내부 크래시

Question

Google은 태그를 지원하는 SUR40 애플리케이션을 개발 중입니다. 그러나 때로는 태그를 이동할 때 TagVisualizationHostAdapter 내부에서 크래시를 재현하는 것이 이상하고 어렵습니다. TagVisualizationHost 역할을하는 ScatterView가 있습니다.

스택 추적 아래. 누구 아이디어?

나는 이것이 이전 게시물입니다 알지만, 오늘이 같은 오류에 떨어졌다. 좀 더 테스트를 해본 결과 오류가 태그와 표면 사이의 부적절한 접촉과 관련이 있다고 생각됩니다. 제 경우에는 코드가 여전히 VisualizationAdded 이벤트 핸들러 안에있을 때 태그를 이동하거나 제거하면 발생하는 것으로 보입니다. 다른 이유가 있다는 것을 알고 있다면 여기에서 공유하고 싶습니까? Thx 줄리앙
