Windows 8의 스플래시 화면에 진행률 링을 추가하는 방법은 무엇입니까?

Question

C# 및 XAML을 사용하여 Windows 8 메트로 앱에서 시작 화면을 활성화하고 진행률 링을 추가해야합니다. 확장 스플래시 화면을 추가했지만 전혀 표시되지 않습니다! 아무도 나에게 이걸하는 법을 말해 줄 수 있니?

Answer 1

확장 된 시작 화면을 사용하면 올바른 길을 걷고 있습니다.

당신은, 실행되는 샘플 및 퀵 스타트로 시작이 작동하는지 확인해야 당신 http://msdn.microsoft.com/en-us/library/windows/apps/xaml/Hh973049%28v=win.10%29.aspx http://code.msdn.microsoft.com/windowsapps/Splash-screen-sample-89c1dc78

샘플이 작동하고 코드가 아닌 경우 두 코드간에 다른 것을 찾으거나 코드를 샘플로 마이그레이션하십시오. XAML 측면에서도 뭔가 잘못되었을 수 있습니다.
