Я разработал веб-сайт с использованием встроенного шаблона Visual Studio 2012 для сайта asp.net.SQL Connection issue
Он отлично работал с сервером разработки ASP.NET.
Когда я загрузил веб-сайт в IIS. Я столкнулся с ошибкой, упомянутой ниже, когда я пытался войти в систему.
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: 50 - Local Database Runtime error occurred. Cannot create an automatic instance. See the Windows Application event log for error details.

If you are deploying to a cloud environment that has multiple web server instances,
you should change session state mode from "InProc" to "Custom". In addition,
change the connection string named "DefaultConnection" to connect to an instance
of SQL Server (including SQL Azure and SQL Compact) instead of to SQL Server Express.
