메트로 앱의 백그라운드 전송 (업 로더) 진행률은 다음과 같이 1 초 이내에 1MB보다 큰 파일에 대해 100 %를 제공합니다.메트로 앱의 백그라운드 전송 (업 로더) 진행 문제
*Running: c5593753-d155-425a-8e25-6b1f90bbff85

따라서 언젠가 업로드가 완료된 후 내 진행률 표시 줄도, wrong.Now의 코스 100 %를 보여주고 난 다음 얻을 :
*Progress: c5593753-d155-425a-8e25-6b1f90bbff85, Status: Completed
- Sent bytes: 1310245 of 1310245 (100%), Received bytes: 49 of 49
Completed: c5593753-d155-425a-8e25-6b1f90bbff85, Status Code: 200
- Response updated; Header count: 9*
그래서 어떤 의미에서 업 로더가 작동 하지만 다시이 잘못된 원인은 파일을 100 %, actual.I 완료하지 않은 10 MB의 파일을 테스트하고있다 고소는 여전히 동일합니다. 100 % 진행 상태와 "완료 됨"상태는 3 분이 경과 한 후에 만 발생합니다.
동일한 업로드 샘플 인 http://code.msdn.microsoft.com/windowsapps/Background-Transfer-Sample-d7833f61을 사용하고 있습니다. 다음과 같이 내가 사용하고있다
