[C#/WINUI3/COMMUNITY TOOLKIT/.NET8] RotationInDegreesAnimation 엘리먼트 : 회전 애니메이션 만들기

■ RotationInDegreesAnimation 엘리먼트를 사용해 회전 애니메이션을 만드는 방법을 보여준다.

※ 이 예제 코드에서 사용된 RotationInDegreesAnimation 엘리먼트는 CommunityToolkit.WinUI.Animations 누겟(버전 : 8.0.240109)을 참조한다.
※ 비주얼 스튜디오에서 TestProject(Unpackaged) 모드로 빌드한다.
※ TestProject.csproj 프로젝트 파일에서 WindowsPackageType 태그를 None으로 추가했다.
