WCF 호출 오류 메시지 - System.ServiceModel.CommunicationException: Internal Server Error

어떤 WCF 호출을 담은 웹 페이지를 호출했을 때의 오류 메시지가 이렇게 나왔습니다.

Server Error in '/' Application.

Internal Server Error 
  Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code. 

 Exception Details: System.ServiceModel.CommunicationException: Internal Server Error

오류 메시지가 매우 불친절하군요. ^^; 원인을 전혀 종잡을 수 없습니다. 다행히, 이 시점의 이벤트 로그를 보면 좀 더 자세한 메시지를 확인할 수 있습니다.

그렇습니다. "System.ServiceModel.DomainServices.Hosting" 어셈블리를 찾을 수 없다는 것으로, 이 어셈블리는 .NET Framework의 기본 설치에 포함되어 있지 않은, 별도 RIA SDK 설치로 사용했던 라이브러리입니다.




그나저나, 이벤트 로그가 문제 해결에 도움이 되는 경우가 많습니다. 가령, 웹 페이지 호출 시 다음과 같은 오류가 발생하는 경우도 있습니다.

현재 WCF를 위해 등록한 scheme은 http 뿐이어서 net.tcp 바인딩을 할 수 없다고 나옵니다. 실제로 해당 경로의 svc를 직접 방문하는 경우 다음과 같은 오류가 발생합니다.

Server Error in '/' Application.

이 오류의 해결 방법은 예전의 글을 참고해,

WCF .svc 호출 시 Could not find a base address that matches scheme net.tcp 예외
; https://www.sysnet.pe.kr/2/0/11062

2가지 바인딩 설정을 IIS의 웹 사이트에 적용하면 됩니다.
