ASP.NET WebForms 응용 프로그램에서 데이터베이스를 만들려고합니다

Question

WebForms 응용 프로그램이 데이터베이스를 만들기 위해 엔티티 프레임 워크에 액세스하는 이유는 무엇입니까? 내 코드와 web.config에서 EF에 대한 모든 참조를 제거했습니다. InProc 세션 상태를 사용하려고합니다. 그러나 내 세션이 만료되거나 응용 프로그램 풀이 브라우저에서 호출을 재활용하면 긴 스핀이 발생하고 궁극적으로 EF에서 데이터베이스를 만들려고하는 예외가 발생합니다.

 

A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections. (provider: SQL Network Interfaces, error: 26 - Error Locating Server/Instance Specified) 
    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.
