Microsoft.SmartDevice.DeviceAgentTransport 네임스페이스
업데이트: 2007년 11월
이 네임스페이스에는 스마트 장치 연결 API의 장치 부분을 구성하는 형식이 들어 있습니다. 이 네임스페이스를 참조하고 사용하는 관리되는 스마트 장치 응용 프로그램을 장치 에이전트 응용 프로그램이라고 합니다. 스마트 장치 연결 API를 사용하는 데스크톱 응용 프로그램은 장치 에이전트를 장치에 배포하고 패킷 데이터를 교환하여 장치 에이전트와 통신할 수 있습니다. 이 라이브러리를 사용하면 스마트 장치 연결 API가 장치 상호 연결을 처리하고 메커니즘 세부 정보를 전송하는 동안 장치와 데스크톱 간에 프로그래밍 방식으로 데이터를 교환할 수 있습니다.
스마트 장치 프로젝트에서 Microsoft.SmartDevice.DeviceAgentTransport를 사용하려면 다음 작업을 수행하십시오.
스마트 장치 프로젝트에서 Microsoft.Smartdevice.DeviceAgentTransport.dll 어셈블리(drive:\Program Files\Common Files\Microsoft Shared\CoreCon\1.0\Target\Microsoft.Smartdevice.DeviceAgentTransport.dll)에 대한 참조를 추가합니다.
네이티브 DeviceAgentTransport.dll 라이브러리(drive:\Program Files\Common Files\Microsoft Shared\CoreCon\1.0\Target\wce400\cpu\DeviceAgentTransport.dll)와 관리되는 Microsoft.Smartdevice.DeviceAgentTransport.dll 어셈블리를 스마트 장치에 배포합니다.
자세한 내용은 스마트 장치 연결 API를 사용하여 장치 제어 및 연습: 데스크톱 및 장치 응용 프로그램 사이에서 데이터 교환을 참조하십시오.
