Question

WPF 프로젝트에서 WCF 서비스를 사용하고 있습니다. 나는 많은 양의 데이터를 가지고 있는데, 약 847 000 레코드가 테이블에있다. 이 예외는 클라이언트 측에서 throwed되는 VM에서

의 App.config에서

proxy.ServicesClient client = new proxy.ServicesClient(); 
var result = client.GetCustomers(); // here throws ('ComunicationException was unhandled by user code: The underlying connection was closed: The connection was closed unexpectedly.') 

의 Web.config에서

참고 : 1. 그것을 많은 양의 데이터로 작동하지 않습니다. 이 경우 테이블에 약 847 000 개의 레코드가 있습니다. 작은 데이터로 완벽하게 작동합니다 (약 5000 - 6000 개의 레코드로). 2. SQL 서버에서 검색된 모든 레코드가 내 DAL로 디버깅됩니다. 이 예외는 클라이언트에서이 서비스 기능을 호출 한 후 5-10 초 동안 발생합니다.
