ViewModelViewHost 전환을 비활성화하는 방법

Question

내 ReactiveUI WPF 응용 프로그램에서 ViewModelViewHost을 사용하여 임의의 viewmodel에 대한보기를 표시합니다. 뷰 모델을 변경할 때 컨트롤은 전환으로 뷰를 페이드 인/아웃합니다. 이 애니메이션을 비활성화하고 싶습니다. 전환 속성을 찾았지만 전환을 변경하는 데만 사용할 수 있으며 비활성화하지 않는 것 같습니다.

이렇게 할 방법이 있습니까?

당신은 0으로 모든 애니메이션의 Duration 속성을 설정 예에 의한 default template for the TransitioningContentControl을 수정할 수 :

      Router="{Binding Router, Mode=OneTime}" 
      HorizontalContentAlignment="Stretch" 
      VerticalContentAlignment="Stretch">
