사용자 코드에 의해 System.Data.EntityException이 처리되지 않았습니다.

Question

C#, ASP, .NET, Visual Studio 또는 Azure에 대한 경험이 거의 없습니다. 나는 (나는 아직도이 과정을 이해하지 못하는) 푸른에 배포 할 때 벌금을 수행하는 웹 응용 프로그램을 가지고,하지만 난 디버그를 실행할 때 -> 디버깅 시작은 비주얼 스튜디오 2012 년,이 오류가 얻을 :

을 나는 필수적인 배경 독서를위한 제안뿐만 아니라 그것을 어떻게 분류하는지에 대한 조언을 주셔서 감사합니다.

감사합니다.

편집 :

내 연결 문자열의 Web.config에서이 있습니다 :

<!-- local --> 
    <add name="Entities" connectionString="metadata=res://*/Models.Awesomeness.csdl|res://*/Models.Awesomeness.ssdl|res://*/Models.Awesomeness.msl;provider=System.Data.SqlClient;provider connection string=&quot;data source=.;initial catalog=Awesomeness;integrated security=True;multipleactiveresultsets=True;App=EntityFramework&quot;" providerName="System.Data.EntityClient" /> 

Answer 1

디버그에 연결 문자열을 확인합니다.

Answer 2

은 저를 위해, 웹 구성 파일에서 ConnectionString에서, 나는

integrated security=True; 

를 제거하고 그것은 바람처럼 일!

Answer 3

도구> 데이터베이스에 연결을 클릭하십시오. SQL Server 데이터베이스에 연결을 시도하십시오. 그럴 수 없다면 연결 문자열이 아님을 의미합니다. 이 오류가 있습니다.

"A network-related or instance-specific error occurred while establishing a connection to SQL Server." 

오류를 검색 할 수 있으므로 온라인상에서 많은 도움을 얻을 수 있습니다.

Visual Studio에서 데이터베이스에 연결할 수 있고 데이터베이스를 클릭하면 속성 창에 연결 문자열이 표시됩니다. 연결 문자열을 응용 프로그램에 복사하여 지나칠 수 있습니다. 그러면 올바른 것으로 알 수 있습니다.
