[C#/WINUI3/.NET8] ListView 엘리먼트 : ItemTemplate 속성을 사용해 항목 표시하기

■ ListView 엘리먼트의 ItemTemplate 속성을 사용해 항목을 표시하는 방법을 보여준다.

※ ItemTemplate 및 DisplayMemberPath를 동시에 사용할 수 없다. 두 속성을 모두 설정한 경우 예외가 발생한다.
※ 비주얼 스튜디오에서 TestProject(Unpackaged) 모드로 빌드한다.
※ TestProject.csproj 프로젝트 파일에서 WindowsPackageType 태그를 None으로 추가했다.
