AppHarbor의 새 MVC4 응용 프로그램에 오류가 발생했습니다. 요청한 .Net Framework 데이터 공급자를 찾을 수 없습니다. 설치되지 않을 수도 있습니다.

Question

Ghit을 사용하여 AppHarbor에 MVC4 응용 프로그램을 배포했으며 AppHarbor 응용 프로그램 프로젝트에 SQL Server 추가 기능을 추가했습니다. 이 프로젝트는 잘 구축하고 내가 로그인 버튼을 내 응용 프로그램의 URL로 이동하여 클릭하면 내가 다른 글에서 무엇을 말할 수에서

내가 내 연결 문자열을 가진 데 문제가 있다는 것입니다 수 데이터 베이스. 그러나 AppHarbor에서 제공된 연결 문자열을 복사하여 web.config에 저장했습니다.

지금까지 로컬 호스트에서만 내 앱을 실행했고 모든 것이 항상 정상적으로 실행되었습니다. 누구든지 조언을 해 주실 수 있습니까?

Answer 1

밝혀졌습니다. 두 응용 프로그램 연결 문자열에 새 SQL Server 연결 문자열이 포함되지 않았습니다. 대부분의 응용 프로그램은 사용자 정의 연결 문자열을 사용하지만 DefaultConnection은 로그인 및 등록 페이지에 사용되었습니다.

나를 위해 제공된 연결 문자열을 DefaultConnection에 추가하면 모든 것이 정상적으로 작동합니다.
