Мне никогда не жалко средств на свое любопытство

Почему не запускается sql сервер?

Использую EntityFramework
Сервер без проблем запускаться на моем ПК, но как только я публикую приложение на raspberry pi c windows 10 iot то получаю исключение

.\TestApp.exe : Unhandled exception. Microsoft.Data.SqlClient.SqlException (0x80131904): 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: SNI_
PN11, error: 52 - Unable to locate a Local Database Runtime installation. Verify that SQL Server Express is properly in
stalled and that the Local Database Runtime feature is enabled.)
