이 Xaml은 유효하지 않습니다 ... 이유를 이해하지 못합니다

Question

xaml에 이상한 문제가 있습니다. wp 용 Visual Studio에서는 xaml이 유효하지 않다고 알려주지 만 앱을 실행하면 제대로 작동합니다.

I의 (a longlistselector의 차이) 튜토리얼을 따라 여기에서 한 : [http://msdn.microsoft.com/en-us/library/windowsphone/develop/hh286418(v=vs .105) .aspx] [1]

어떻게하면 좋을지, longlistselector는 이미지와 연락처 이름을 보여줍니다.

구조체를 표시합니다 : 도움이 모든 일에

namespace Friends_And_Money 
{ 
    class ContactStruct 
    { 
     public string FirstName 
     { 
      get; 
      set; 
     } 

     public WriteableBitmap Photo 
     { 
      get; 
      set; 
     } 

     public ContactStruct(string name, WriteableBitmap photo) 
     { 
      this.FirstName = name; 
      this.Photo = photo; 
     } 

    } 
} 

감사합니다.

새로운 세부 정보 : 오류는 datatemplate AddrBookItemTemplate에 서명되어 있으며 이미지 원본 특성을 남겨두면 오류가 사라진다는 점에 유의했습니다. 그래서 바인딩이있는 것처럼 보입니다.

Answer 1

wp 용 비주얼 스튜디오 xaml은 유효하지 않지만 앱을 실행할 때 제대로 작동합니다.

디자이너를 무시하십시오. 그것은 다소 변덕 스럽습니다.

Answer 2

잘못된 복사/붙여 넣기 일 수도 있지만 첫 번째 요소 (<phone:PhoneApplicationPage>)가 가까이 있지 않습니다.
