방법: 사용자 지정 기능 커넥터 만들기
다음 코드 예제에서는 사용자 지정 기능 커넥터를 구현하는 방법을 보여 줍니다. 전체 솔루션은 WPF and Silverlight Designer Extensibility Samples 사이트의 Feature Connector 샘플을 참조하십시오.
예제
다음 코드 예제에서는 FeatureConnector<TFeatureProviderType> 클래스에서 파생하여 DiagnosticsMenuProvider라는 사용자 지정 기능 공급자와 IDiagnosticsService라는 사용자 지정 서비스를 연결하는 방법을 보여 줍니다.
